EA Javelin anticheat: repeated BSOD (6/7 same fault) + launcher crash 0xC0000005
Product: Apex Legends Platform: Steam-PC Windows: 11 24H2 (26100.6584) and 25H2 (26200.6584) — reproducible on BOTH CPU/GPU: RTX 4060 Laptop, 16GB RAM, single NVMe (YMTC PC300-1TB-B) CRASHES A — KERNEL BSOD (7 times between Oct 15-16, ALL while Apex was running): #1 10-15 13:05 0x0000000A (0x00007fffffff0000, 0xff, 0xea, 0xfffff80680e597ac) 25H2 #2 10-15 15:35 0x0000000A (0x00007fffffff0000, 0xff, 0x8a, 0xfffff803768597ac) 25H2 #3 10-15 17:24 0x0000003B (0x00000000c0000005, ...) WER bucket: AV_eaanticheat!DriverEntry #4 10-15 18:06 0x0000000A (0x00007fffffff0000, 0xff, 0x2a, 0xfffff800822597ac) 25H2 #5 10-15 19:42 0x0000000A (0x00007fffffff0000, 0xff, 0x4a, 0xfffff804d44597ac) 25H2 #6 10-16 07:57 0x0000000A (0x00007fffffff0000, 0xff, 0x8a, 0xfffff800868597ac) 25H2 #7 10-16 14:47 0x0000000A (0x00007fffffff0000, 0xff, 0xea, 0xfffff805cbe597ac) 24H2 (after rolling back) Key point: in all 6 of the 0x0000000A crashes - parameter 1 is exactly 0x00007fffffff0000 - parameter 2 (IRQL) is exactly 0xff — outside the legal IRQL range of 0-15 - parameter 3 is an abnormal value (0xea / 0x8a / 0x2a / 0x4a) instead of 0 or 1 (read/write) - the faulting instruction address ends with 0x97ac every single time (high bits differ only by ASLR) Random hardware memory errors cannot land on the identical instruction 6 times in a row. This is the same code path inside the EA driver crashing repeatedly, with a corrupted exception context. CRASHES B — USER-MODE LAUNCHER (during game launch, still happening after the rollback to 24H2): EAAntiCheat.GameServiceLauncher.dll (v3.10.1.0, timestamp 0xeafd060e) -> 0xC0000005, offset 0x183E430 EAAntiCheat.GameServiceLauncher.exe (v1.0.48125.0) -> 0xC0000409 (fail-fast) Dumps: C:\ProgramData\eaanticheat\Crashdumps\PACKER_*.dmp My own minidump analysis of the PACKER dumps: every single 0xC0000005 has the faulting address inside EA's own modules (never a third-party DLL): EAAntiCheat.GameServiceLauncher.dll + 0x9B9331 -> read 0x0 EAAntiCheat.GameServiceLauncher.dll + 0x2EA5411 -> read 0xFFFFFFFFFFFFFFFF EAAntiCheat.GameServiceLauncher.dll + 0x2A6EB77 -> read 0xFFFFFFFFFFFFFFFF EAAntiCheat.GameServiceLauncher.dll + 0x24C49B9 -> read 0xFFFFFFFFFFFFFFFF EA\AC\EAAntiCheat.GameService.dll + 0x2B5D014 -> read 0xA0CE44F290 The dumps only load system DLLs + GameServiceLauncher.dll + preloader_l.dll, so the crash happens in the very first milliseconds, before the game executable is even loaded. Digital signatures are valid. ALREADY TRIED (all had no effect): 1. Full game reinstall (deleted via Steam, re-downloaded) 2. Deleted C:\Program Files\EA\AC and reinstalled with the official installer shipped in the game folder: EAAntiCheat.Installer.exe --noui --install --read-cfg (exit code 0, components updated to the latest build) 3. Verified with PE compile timestamps that the running launcher dll/exe ARE the newest files (no stale-file issue) 4. Rolled Windows back from 25H2 to 24H2 (uninstalled enablement package KB5054156) — crashes persisted on 24H2 5. Removed Tencent ACE anti-cheat completely; exited all accelerator kernel drivers (NetEase UU, Xunyou) 6. Secure Boot enabled; VBS/HVCI disabled; clean reboots after each step (checked PendingFileRenameOperations) 7. Disk SMART healthy, chkdsk clean, no Code Integrity driver blocks, PCIe ASPM disabled 8. Removed -dev launch option, disabled Steam overlay, removed Nahimic injection components WHAT I'M ASKING: Please have the anti-cheat team check whether there is a known defect in the eaanticheat kernel driver and in EAAntiCheat.GameServiceLauncher.dll, or whether a specific newer build is required. If you need further logs/dumps (raw .dmp files, full MEMORY.DMP, WER reports), tell me how to upload them and I will provide them. The crash points are consistently INSIDE EA's own modules, so please don't ask me to repeat the local troubleshooting steps listed above.
Apex Legends on Steam Stuck at Starting EA Javelin AntiCheat – Error 87
Title: Apex Legends on Steam Stuck at “Starting EA Javelin AntiCheat” – Error 87 Hi EA Support, I'm playing Apex Legends through Steam, but the game gets stuck on the loading screen and never reaches the main lobby. The loading messages include “Validating game environment,” “Starting EA Javelin AntiCheat,” and “Launching game.” I've already tried: Verifying the integrity of Apex Legends game files through Steam. Disabling Steam Overlay. Checking Task Manager, where r5apex.exe does not appear. Opening EAAntiCheat.Installer.exe, but Apex Legends does not appear in the game selection dropdown. Starting EAAntiCheatService through Windows Services, which results in Error 87: The parameter is incorrect. Dota 2 and Valorant work normally on the same PC. Could you please help me fix the EA Javelin AntiCheat installation for the Steam version of Apex Legends? I would prefer not to reinstall the entire game again. Thank you.
Apex crashes on launch (Steam and EA app)
Apex Legends crashes a few seconds after launch with the following error (In steam and in EA app): An unexpected game shutdown was detected (0xC0000409) Windows Event Viewer logs the following under EA Javelin Anticheat, Event ID 1000: The game r5apex_dx12.exe exited unexpectedly, exit code: 0xC0000409 The issue occurs when launching Apex Legends through both Steam and the EA app. I had not played Apex Legends for several months, so I cannot confirm whether the issue started exactly with the September 29, 2026, Javelin transition. However, the game did not have this problem the last time I played it. System specifications OS: Windows 11 26H2, build 26300.9550 CPU: AMD Ryzen 7 5700X GPU: NVIDIA GeForce RTX 5060 Ti 16 GB RAM: 32 GB DDR4 Platform: Steam and EA app Additional Event Viewer errors I also found an EA Javelin Anticheat error, Event ID 1000, with the message: Failed retrieving service path. This event was recorded on October 8, 2026, at 12:54 PM. I checked the EA AntiCheat service: Service name: EAAntiCheatService Executable path: C:\Program Files\EA\AC\eaanticheat.gameservice.exe The executable exists. Its digital signature is valid and verified, issued to Electronic Arts, Inc. The service is configured for demand start and is stopped when checked while the game is not running. Troubleshooting already attempted -Verified Apex Legends game files through Steam. -Updated Windows to build 26300.9550 and restarted. -Updated NVIDIA graphics drivers and Windows. -Repaired/reinstalled EA AntiCheat/Javelin. (Even removing the anticheat and letting the game update it by itself) -Ran the game and anticheat as administrator + Firewall is not blocking them. -Disabled overlays and background applications. -Performed a clean boot; the issue persisted. -Cleared the Steam download cache. -Reset network settings. -Checked other anti-cheat services, including Riot Vanguard, Easy Anti-Cheat, and BattlEye. Stopping the Vanguard service did not resolve the issue. -Checked the EA AntiCheat service executable path and digital signature. -Moved Apex Legends from the F: drive to the C: drive and tested again. The same 0xC0000409 crash persisted. None of these steps resolved the crash. I also have the issue that Apex Legends does not appear as an option when I try to install it manually using the EA Javelin Installer. (I also tried installing one of the other options, but neither worked)

[BUG] Javelin splash silently exits and Apex won't launch since EAC→EAAC switch
Apex Legends has not launched a single time on my machine since the September 29 switch from EAC to EAAC. When I click Play in Steam, the EA Javelin splash (EAAntiCheat.GameServiceLauncher.exe) shows "starting ea javelin anticheat" for a few seconds and just exits while the game never starts at all. Additional observations / error details: 1. Every time the splash window disappears, the "eventvwr.msc" (Windows Event Viewer) logs this error from "EA Javelin Anticheat": ExitType: 0x6DDDE3D53317900F (0x815E4FB258B85009) Before an anticheat update near 09-30, the same symptom logged as "ExitType: 0xC102E1B1166EFBC9 (0xAF7CD40A3C7542BE)" 2. EAAntiCheat.Installer.exe exits normally both with "--update" and "--update-check" args. The EAAntiCheat.GameService.exe started by the service, however, always exits with code 0xffff900f (before the update it was 0xfffffbc9). 3. As I have observed no "r5apex_dx12.exe" instance was even started by the launcher. 4. I downloaded another free game that uses EA Javelin ("skate."), and it launches and plays without any problem — so this looks specific to Apex's Javelin integration, not Javelin in general. 5. Other games with anticheat work fine: Games using EasyAntiCheat, AntiCheatExpert and BattleEye all run without issue. I've also downloaded another free game that uses EA Javelin ("skate.") and it launches and plays without any problem — so this looks specific to Apex's Javelin release, not Javelin in general. Tried workouts: (sadly none changed the outcome) Multiple reboots tries Verified game file integrity Moved the game to a different drive "sfc /scannow" Tried different ISPs Toggled Memory Integrity (HVCI/VBS) option in Windows Security Center Uninstalled Antivirus Uninstalled Radmin VPN & Proxifier Uninstalled and manually reinstalled Javelin via EAAntiCheat.Installer.exe using both GUI and `"C:\Program Files\EA\AC\EAAntiCheat.Installer.exe" --noui --uninstall` Uninstalled Javelin and start apex to let the launcher reinstall it automatically System Information: OS：Microsoft Windows 11 Pro 10.0.26200 Build 26200（With Secure Boot + TPM） CPU：12th Gen Intel(R) Core(TM) i7-12650H GPU：NVIDIA GeForce RTX 4060 Laptop GPU（Graphic Driver Version：616.92） RAM：32.0 GB DDR5 / VRAM：8.0GB Steam Patch：1788652215 (Stable Channel) I was wondering what actually causes "GameService" to stop itself about three seconds after the driver loads successfully, and what do 0xffff900f and 0xfffffbc9 mean? And is there any diagnostic mode or log flag we can enable on the Javelin service so it at least tell legit players rejection reasons/trace ids instead of just exit silently? For players who are genuinely cheating, bans can be issued after a randomized delay. Hard-blocking with no warning doesn't help either side — it doesn't keep cheaters from learning what tripped the detection and adapting, and it also locked legitimate players out frustratingly. I'd really appreciate this getting looked at by someone on the anti-cheat side rather than being closed with a reinstall/clean-boot template, since the game has been completely unplayable since the switch.🥺Apex Legends Ban Appeal No Response After 12 Days | Case #255841399
Hello @Community Manager, I’m creating this thread to request guidance regarding my pending Apex Legends Terms of Service appeal. It has now been 12 days since I submitted my appeal, and I have still not received a response from the review team. Case Details: Game: Apex Legends Platform: Steam (AppID: 1172470) Case Number: #255841399 Appeal Submitted: October 3, 2026 Current Status: New / In Progress Time Elapsed: 12 days Previous Thread I previously raised this concern in the following thread: Overdue Ban Appeal Inquiry – Case #255841399 (Diagnostic Evidence Submitted) In that discussion, a Community Manager advised me that the Terms of Service team could take up to 10 days to respond and specifically warned me not to reopen my ticket, as doing so could move it to the back of the queue. I have followed that advice and have not reopened my existing case. Steps Already Taken Game File Verification: Verified my Apex Legends game files through Steam. Diagnostic Submission: Submitted client, service, and anti-cheat diagnostic logs through the official EA Error Reporter. Additional Evidence: Provided DxDiag logs and relevant session details to support my appeal. Despite these steps, my appeal remains in progress, and I have not received any response or acknowledgment from the review team after the stated 10-day timeframe. Request for Guidance I understand that Community Managers cannot directly investigate anti-cheat telemetry or overturn sanctions. I am not asking for special treatment or an immediate decision. I would simply appreciate clarification on the following: Is it normal for an appeal to remain in New / In Progress status beyond the stated 10-day timeframe? Should I continue waiting without taking any further action? Is there an appropriate way to confirm that my existing appeal and submitted diagnostic evidence have reached the correct review queue? I am creating this follow-up thread because I want to understand the correct next steps without accidentally delaying my existing appeal. I would be grateful if a Community Manager could review my previous thread and provide guidance regarding Case #255841399. Thank you for your time and assistance
