BF6 (Steam) crashes after logo – Javelin Anti-Cheat / EA AntiCheat issue?

Hi,

I’m having a persistent crash issue with Battlefield 6 (Steam, PC) that seems to be related to EAAntiCheat / Javelin and possibly Windows 11 24H2 Insider builds.

I would really appreciate it if someone from the dev / anti-cheat team could confirm whether this is a known issue or a compatibility problem with my OS.

Environment

- Game: Battlefield 6
- Platform: Steam, PC
- OS: Windows 11 Pro 10.0.26200.7171 (25H2 build)
- Anti-cheat: EA Javelin AntiCheat (EAAntiCheat)
- I have previously played BF6 for about 88.6 hours on this same PC.

Symptoms

1. Launch BF6 from Steam.
   2. “Javelin Anti-Cheat is starting…” window appears.
   3. A small BF6 window opens, then maximizes and shows the Battlefield 6 SEASON 1 logo.
   4. Immediately after the logo appears, the game crashes to desktop.
   5. No in-game error message is shown.

This happens 100% of the time.

What I have already tried

I’ve gone through all the steps in the official EAAntiCheat article and the suggestions from EA Help support:

1. I also tried uninstalling and reinstalling Battlefield 6 via Steam.
2. Repair / reinstall EAAntiCheat
    - Ran EAAntiCheat.Installer.exe as admin both from:
      - C:\Program Files\EA\AC\EAAntiCheat.Installer.exe (229MB)
      - ...\Steam\steamapps\common\Battlefield 6\EAAntiCheat\EAAntiCheat.Installer.exe (167MB)
    - Selected Battlefield 6 in the drop-down, used "Repair", and also tried "Uninstall → Install".
    - Note: the EAAntiCheat.Installer.exe inside the BF6 game folder initially looked like an older version, because at first it didn’t list "Battlefield 6" in its game selection drop-down. The global one under C:\Program Files\EA\AC\ does show "(installed)Battlefield 6".
3. Service configuration
    - Deleted and recreated the service:
      - sc stop EAAntiCheatService
      - sc delete EAAntiCheatService
    - Let the installer recreate it.
    - Current service config (sc qc) shows:
        BINARY_PATH_NAME : "C:\Program Files\EA\AC\eaanticheat.gameservice.exe"
    - The file EAAntiCheat.GameService.exe exists in that both AC and BF6 folder.
4. Exploit Protection
    - Windows Security → App & browser control → Exploit protection → Program settings:
      - Added bf6.exe:
          - Control flow guard (CFG): override system setting → Off
          - Force randomization for images (Mandatory ASLR): override system setting → Off
      - Added EAAntiCheat.GameService.exe and tested with mitigations disabled:
          - EAAntiCheat.GameServiceLauncher.exe
      - Rebooted after changes.
5. Directly running EAAntiCheat.GameService.exe
    - ...support told me “Please run EAAntiCheat”.
    - So, in C:\Program Files\EA\AC\ the file is actually named EAAntiCheat.GameService.exe_e (with a trailing "_e"), so it cannot be executed directly.
      - Instead, I ran EAAntiCheat.GameService.exe from the Battlefield 6 game folder.
        → Behavior is identical to launching from Steam: Javelin window → small BF6 window → fullscreen logo → immediate silent crash.
6. Other standard troubleshooting
    - Verified / repaired BF6 files in Steam.
    - Disabled Windows Defender real-time protection and any third-party AV while reinstalling.
      - Tried launching Steam as administrator.
      - Deleted / renamed BF6 config folders under Documents to let the game recreate them.

None of these steps changed the behavior.

Why I suspect an OS / AntiCheat compatibility issue

- EAAntiCheat / Javelin is a kernel-level anti-cheat.
- My OS is Windows 11 Pro Insider Preview 10.0.26000.7171 (25H2).
- There are already reports for other EA titles where EAAntiCheat does not officially support Insider / early 25H2 builds and causes crashes or error 87, etc.

Given that:

- EAAntiCheat service now starts correctly.
- The crash happens right after the BF6 logo, with:
  - "bf6.exe exited unexpectedly, exit code: 0x80000000"
  - Application Error 0xc0000005 in bf6.exe

…it looks like BF6 + Javelin may not be fully compatible with this Windows 11 Insider / 25H2 build.

Questions

1. Is Battlefield 6 + EAAntiCheat officially supported on Windows 11 pro Insider / 25H2 builds (e.g. 10.0.26000.x), or only on stable builds like Windows 11 24H2?
   2. If Insider / 25H2 is not supported, can someone from EA please confirm that rolling back to a supported stable Windows build is currently the only workaround?
   3. If it should be supported, could this be escalated to the BF6 / AntiCheat (Javelin) dev team?

If anyone else is running BF6 on a similar Windows 11 pro 25H2 / Insider build, I’d also be interested to hear whether you can launch the game successfully with Javelin AntiCheat enabled.
