Instant close, no crash report, no on-screen error

Hello,

I’m experiencing a sudden crash issue on EA Sports FC 26 on PC.
The game closes without any error message, both through Steam and EA App, usually during a match or menu transition.

Technical details:

System: Windows 10/11 Pro 64-bit

GPU: NVIDIA

CPU : i7 13700k

Platform: Steam + EA App

Type of crash: instant close, no crash report, no on-screen error

Windows Event Viewer logs:
EAAntiCheatService
The game fc26.exe exited unexpectedly, exit code: 0xC0000409

Previously, I also had:

EAAntiCheatService
The game fc26.exe exited unexpectedly, exit code: 0xC0000005

and sometimes:

EAAntiCheatService
Title is not installed. (fc26)

Steps I’ve already tried:

Full reinstall of the game and EA AntiCheat

Manually deleted the folder C:\Program Files\EAAntiCheat before reinstalling

Ran Steam, EA App, and fc26.exe as Administrator

Verified game files via Steam

Fully updated NVIDIA drivers and Windows

Disabled all overlays (Steam, EA App, Discord, NVIDIA, Xbox Game Bar, etc.)

Tested the game in Windows diagnostic startup (msconfig)

No third-party antivirus, only Windows Defender active

Issue:

Despite all these steps, the game still crashes with error 0xC0000409, which seems related to a memory or EA AntiCheatService conflict.

Could you please help me with the following:

How to completely reset or reinstall EA AntiCheatService,

Whether there’s a known fix or update for this specific 0xC0000409 crash on PC,

How to generate or send a detailed crash/diagnostic report for you to review.

Thank you in advance for your help,
