Ten EAAntiCheatService terminations on 24-25 August: 11:38, 12:05, 13:29, 13:53, 16:19, 17:10, 17:11, 17:27, and 01:27 F1_25.exe never records a fault. WER LocalDumps was configured for it and C:\D...

adding current report code MRPX-BMRLRLTV-BPDD (not crashed yet - note this session doesnt have resize racoon running and game is windowed on one screen. i made those logs during this session
TITLE: F1 25 - EAAntiCheatService terminates repeatedly, game closes to desktop with no error
Platform: PC (Steam)
Report Code: *(paste the code from the Pause menu, bottom left, from a session that crashed)*
SUMMARY
F1 25 closes to desktop with no error message, repeatedly, 25 to 90 minutes into a session.
The game process itself never faults. Windows records no crash for F1_25.exe. What
terminates is EAAntiCheatService, and the game goes down with it. This happened ten
times in roughly fifteen hours.
WHAT WINDOWS RECORDS
Every occurrence produces one identical System log entry and nothing else:
The EAAntiCheatService service terminated unexpectedly.
Timestamps (24–25 August 2026):
11:38:54 · 12:05:23 · 13:29:53 · 13:53:34 · 16:19:14 · 17:10:52 · 17:11:40 · 17:27:11 · 01:27:33
No bugcheck. No WHEA event. No display driver timeout (no event 4101). No Code Integrity
block. The machine stays up; only the game disappears.
THE GAME PROCESS NEVER FAULTS
I configured WER LocalDumps for F1_25.exe pointing at C:\Dumps. The registry key was
verified as correctly registered. After ten crashes, C:\Dumps is empty. The game is
being terminated rather than crashing.
One earlier fault was recorded for the anti-cheat launcher itself:
Faulting application: EAAntiCheat.GameServiceLauncher.exe, version 1.0.64026.0
Faulting module name: unknown, version 0.0.0.0
Exception code: 0xc0000005
Fault offset: 0x00007ffd92332a9e
Bucket: PCH_88_FROM_unknown
The WER report for that fault lists only two non-Microsoft modules loaded in the process:
EAAntiCheat.GameServiceLauncher.exe and preloader_l.dll. Both are EA's own files.
Nothing third-party was injected into it.
WHAT I HAVE ALREADY ELIMINATED BY DIRECT TEST
Each of these was removed or disabled, and the crash still occurred:
- NVIDIA App overlay (processes killed, NvContainer service stopped)
- DisplayFusion (uninstalled)
- Resize Raccoon (closed; also tested on a single screen with it not running)
- AutoHotkey (removed)
- Triple-screen span (tested on a single 2560x1440 display)
- Second GPU, an NVIDIA T1000, disabled in Device Manager
- EA Anti-Cheat reinstalled twice via EAAntiCheat.Installer.exe
- F1 25 fully uninstalled and reinstalled from Steam (~81 GB)
- Windows Defender exclusions added for the game folder, C:\Program Files\EA\AC, and both
EAAC executables
- "Optimizations for windowed games" turned off
- Default high performance GPU forced to the RTX 5090
Platform state verified as normal: Secure Boot On, Kernel DMA Protection On,
WDAC usermode enforcement not enabled, mandatory ASLR not set, no second antivirus.
TWO CONTROLS THAT ISOLATE THIS TO THE ANTI-CHEAT
1. Another Codemasters title runs fine on the same machine. DiRT Rally 2.0 ran for
hours on the same PC, same three screens, same window tooling, same GPU load, with no
crash. Same engine lineage, no kernel anti-cheat.
2. A near-identical second PC runs F1 25 for 15 hours without a single failure. Same
game, same Resize Raccoon setup, same triple-screen span, at a higher resolution
(triple 4K vs triple 1440p). The differences are that this machine has a second GPU (a
T1000, which was disabled during testing and made no difference) and a 14900K rather than
a 14900KS.
