KERNEL SECURITY CHECK FAILURE

Título: F1 25 crashes to desktop / EAAntiCheatService error — nvlddmkm.sys conflict with driver 610.47

Descripción:

F1 25 is crashing to desktop consistently. WhoCrashed analysis identified nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver, Version 610.47) as the root cause of multiple BSODs (KERNEL_SECURITY_CHECK_FAILURE / 0x139). After rolling back the driver, BSODs stopped but EAAntiCheatService now terminates with error %%4294901855 (0xFFFF0017) on every session.

System specs:

• CPU: AMD Ryzen 9 7950X3D

• GPU: NVIDIA RTX 4090

• RAM: 64GB

• Motherboard: ASUS ROG Crosshair X670E Hero

• OS: Windows 11 (26200.8457)

Driver that caused BSODs: NVIDIA 610.47 (nvlddmkm.sys)

Current driver after rollback: NVIDIA 572.83

Steps already taken:

• WhoCrashed confirmed nvlddmkm.sys (610.47) as crash cause

• Clean NVIDIA driver reinstall via DDU

• Rolled back from 610.47 to 572.83 (resolved BSODs)

• Verified game file integrity via Steam

• Reinstalled/repaired EasyAntiCheat via EasyAntiCheat_Setup.exe

• No overlays or third-party monitoring software running

• SFC and DISM scans came back clean

Result: BSODs resolved after driver rollback, but game still crashes to desktop every session due to EAAntiCheatService terminating.
