College Football 27 PC – Repeated EA Javelin AntiCheat Crash / 0xC0000005
COLLEGE FOOTBALL 27 – REPEATED EA JAVELIN ANTICHEAT CRASH / 0xC000000
I am experiencing persistent crashes in EA Sports College Football 27 on PC. After extensive troubleshooting, the evidence strongly indicates that EA Javelin AntiCheat is terminating unexpectedly and causing the game to close.
The problem is highly reproducible and has continued through multiple Windows, driver, security, and hardware/software configuration changes.

CRASH BEHAVIOR
The crash can occur at different points, but it frequently occurs shortly after entering Dynasty mode and opening Recruiting.
In recent testing, the game often lasts approximately one to three minutes after entering Dynasty/Recruiting before abruptly closing.
There is generally no useful in-game error message.
The crash has occurred during Dynasty/Recruiting, during gameplay, after returning from a game to Dynasty, during startup videos, and shortly after game launch.
This makes it unlikely that the problem is tied to one particular Dynasty screen, graphical scene, or gameplay action.
WINDOWS EVENT LOG EVIDENCE
A fresh crash on August 31, 2026 produced the following sequence.
At 11:16:45 AM, Windows Filter Manager reported:
File System Filter 'EAAntiCheat' successfully loaded and registered with Filter Manager.
At 11:18:38 AM, Windows Filter Manager reported:
File System Filter 'EAAntiCheat' unloaded successfully.
At exactly the same time, EA AntiCheat generated the following crash dump:
C:\ProgramData\eaanticheat\Crashdumps\PACKER_277890_15164.dmp
Immediately afterward, Service Control Manager Event ID 7034 reported:
The EAAntiCheatService service terminated unexpectedly.
This same FilterManager unload followed by EAAntiCheatService Event 7034 has happened repeatedly during CF27 crashes.
Additional August 31 examples:
11:04:50 AM – EAAntiCheat filter unloaded
11:04:51 AM – EAAntiCheatService terminated unexpectedly
11:11:16 AM – EAAntiCheat filter unloaded
11:11:17 AM – EAAntiCheatService terminated unexpectedly
11:18:38 AM – EAAntiCheat filter unloaded
11:18:38 AM – EAAntiCheatService terminated unexpectedly
WINDBG ANALYSIS OF FRESH EA ANTICHEAT CRASH DUMP
I analyzed the August 31 crash dump PACKER_277890_15164.dmp using WinDbg.
Process:
eaanticheat.gameservice.exe
EA AntiCheat/Javelin process version:
1.0.27607.0
WinDbg failure bucket:
INVALID_POINTER_READ_c0000005_eaanticheat.gameservice.exe!Unknown
Exception:
0xC0000005 – Access violation
Faulting module:
eaanticheat_gameservice_exe
Faulting module offset:
0x9F88800
Exception IP:
eaanticheat_gameservice_exe+0x9f88800
Faulting instruction:
jmp rax
At the time of the crash:
RIP = 00007ff76b5c8800
RAX = f9647607593d7c70
RBP = 9c8d635d9f532585
The relevant WinDbg disassembly immediately before the crash is:
add rsp,3A8h
pop rbx
pop rbp
pop rdi
pop rsi
pop r12
pop r13
pop r14
pop r15
jmp rax
The exception record reports:
ExceptionCode: c0000005
Attempt to read from address ffffffffffffffff
REPEATED DUMP SIGNATURE
This is not the first EA AntiCheat crash dump I have analyzed.
Multiple independently captured Javelin dumps have repeatedly failed at the same internal EA AntiCheat module offset:
eaanticheat_gameservice_exe+0x9f88800
The faulting instruction has also repeatedly been:
jmp rax
The absolute process address changes, which is expected due to address randomization, but the module-relative offset remains the same.
This appears to be a reproducible failure through the same internal EA AntiCheat/Javelin code path rather than unrelated random crashes.
TROUBLESHOOTING ALREADY PERFORMED
I verified the College Football 27 installation through Steam.
I reinstalled/repaired EA AntiCheat.
I tested clean launches and different portions of Dynasty and gameplay.
I disabled common overlays.
I ran DISM and SFC Windows repair procedures.
The Razer Blade BIOS has been updated to BIOS 1.08.
I have tested multiple Windows builds. The current build is 26200.9278, and the crash persists on this build.
I tested Memory Integrity/HVCI disabled.
I tested Virtualization Based Security disabled.
I tested the Windows hypervisor disabled.
I tested Virtual Machine Platform disabled.
During that test, HypervisorPresent was confirmed False.
The crash continued.
These Windows security settings have since been restored to their normal configuration.
I tested Hardware-Accelerated GPU Scheduling disabled. The crash continued.
ExpressVPN was completely uninstalled. Its expressvpn-pkf and expressvpn-ovpn-dco kernel drivers were confirmed absent. The crash continued.
The Intel XTU kernel component was isolated. The service is XTUComponent and the actual driver is C:\Windows\System32\drivers\iocbios2.sys.
The driver is Intel Corporation Intel(R) Overclocking Device Driver version 7.12.0.18 and has a valid digital signature.
XTUComponent was set to Stopped and Disabled, and the system was rebooted with iocbios2.sys not loaded. CF27 still crashed.
The Razer Control Device / RzCommon was disabled for an isolated test. RzCommon was confirmed Stopped while RzDev_02b7 remained running. The crash continued. RzCommon was restored afterward.
I did not remove RzDev_02b7 because it participates directly in the Razer Blade keyboard and mouse HID stack.
NVIDIA Broadcast and NVIDIA Virtual Audio Device were disabled. The nvrtxvad_WaveExtensible and nvvad_WaveExtensible drivers were confirmed stopped after reboot. The crash continued. They were restored afterward.
NVIDIA Platform Controllers and Framework was disabled. The device was ACPI\NVDA0820\NPCF and the service was nvpcf. After reboot, nvpcf was confirmed Stopped. The crash continued. The device was restored afterward.
The Logitech LampArray kernel driver logi_lamparray was disabled and confirmed Stopped. The crash continued. It was restored afterward.
SUMMARY
Across all of these tests, the EA AntiCheat/Javelin failure has remained essentially unchanged.
The crash has reproduced with and without VBS/HVCI, with and without the Windows hypervisor, without ExpressVPN, with Intel XTU disabled, with Razer Control Device disabled, with NVIDIA Broadcast and Virtual Audio disabled, with NVIDIA Platform Controllers disabled, with Logitech LampArray disabled, with Hardware-Accelerated GPU Scheduling disabled, and across different Windows cumulative builds.
Multiple Javelin dumps continue to fail at:
eaanticheat_gameservice_exe+0x9f88800
with exception:
0xC0000005
and faulting instruction:
jmp rax
The corresponding Windows System log repeatedly reports:
The EAAntiCheatService service terminated unexpectedly.
FILES AVAILABLE
Attached is the complete DxDiag.txt generated August 31, 2026.
I can provide the fresh EA AntiCheat crash dump PACKER_277890_15164.dmp.
I can provide additional older EA AntiCheat/Javelin crash dumps that show the same failure offset.
I can provide Windows Event Viewer logs.
I can provide additional WinDbg output if needed.
REQUEST
Could this report please be escalated to the College Football 27 / EA Javelin AntiCheat engineering team?
At this stage, the evidence appears to show a reproducible failure occurring inside the EA AntiCheat GameService process. I have already performed extensive Windows and third-party kernel-driver isolation without changing the failure signature.
Most important technical information:
Process: eaanticheat.gameservice.exe
Version: 1.0.27607.0
Exception: 0xC0000005
Failure bucket: INVALID_POINTER_READ_c0000005_eaanticheat.gameservice.exe!Unknown
Repeated fault offset: eaanticheat_gameservice_exe+0x9f88800
Faulting instruction: jmp rax
Windows Event: EAAntiCheatService terminated unexpectedly
Fresh dump: PACKER_277890_15164.dmp
If EA engineering needs additional WinDbg commands run against the dump, additional logs collected, or another reproduction captured, I am happy to provide them.
