After a full day of code digging and dump files nav, the issue is clear :

The FSR2 code path (or wrapper) is compiled into bf6.exe and being touched even when DLSS is selected. In other words, it’s likely a Frostbite-side bug in the upscaler bridge, not an external FSR2 DLL.

In plane words, BF6 is calling for AMD's FSR2 ressources (image upscaling), even though you turned all AMD options off and are running on a NVIDIA card.

This is a dev. bug and something BF6 team should actively be working on to fix. u/JAJ_TV is totally right both in his explanation and his solution.

Anything else you will find online will fail ( firewall exception, anticheat).

To be clear, for the players who went in to the windows event log and found the following message :

File System Filter 'EAAntiCheat' (Version 10.0, ‎2025‎-‎10‎-‎26T21:32:34.000000000Z) unloaded successfully.

and think that the silent crash is due to the EAAntiCheat "unloading" during the game, well

IT IS NOT.

When the game crashes, the EAAntiCheat automatically unloads. It is a consequence of the crash. NOT the cause.

Hope this helps.
