EasyAntiCheat_EOSSys does not support bypass IO

Hi, I've been experiencing random crashes while playing Apex Legends. Each time it happens, I notice the following entry in the Event Viewer:

File System Filter 'EasyAntiCheat_EOSSys' (Version 10.0, ‎2025‎-‎07‎-‎28T12:13:02.000000000Z) does not support bypass IO. Supported features: 0x4

After this error appears, the game eventually crashes again during gameplay, and I get kicked from the server. This is especially frustrating during ranked matches, as I have to wait to rejoin and often lose progress.

I've tried multiple troubleshooting steps on my own, but I haven’t been able to resolve the issue. Any help or guidance would be greatly appreciated.

Thanks in advance.

Things I've tested this far.

1. Reinstalled windows 11 pro 24h2 also tested 23h2 no joy.
2. Updated all drivers and windows updates. 
3. Ran easy anti cheat and Apex as admin. 
4. Disabled core isolation
5. Tested loads of nvidea drivers on 577.00 atm.
6. Done a repair on easy anti cheat
7. Removed Amd expo tested no change.

  • I've found a temp fix for this if anyone else is having the same issue. You need to use Nvidea Driver 551.23 and it will stop the crashing for now. Not ideal but it works in apex legends.

    Also switch off windows 11 driver updater as it will force a newer driver.

    Battlefield forced me to the latest AMD driver 25.8.1 but was previously on 24.5.1 so I have to change drivers each time I want to load up a EA game to play?

    I'm not too familiar with AMX GPUs, but if you're having trouble getting things stable, I'd recommend rolling back to the earliest compatible driver for Windows 11. Then work your way forward until you find the most recent version that doesn't cause crashes. Personally, I haven't had a single crash since switching to GPU driver 551.23. You might want to check the release date for that driver and see which AMD driver was current at the same time — it could help narrow things down.
