Yeah, Easy Anti-Cheat is really not happy with your drivers for whatever reason. It might actually be worth trying to repair Easy Anti-Cheat, in case it’s an issue with the service itself. This can be done via the EasyAntiCheat_Setup executable located here: C:\Program Files (x86)\Steam\steamapps\common\Warhammer Vermintide 2\installers\EasyAntiCheat
Edit: Ignore me, I see in your OP that you mentioned you’ve already tried reinstalling Easy Anti-Cheat, apologies!
I’m happy to query this with Easy Anti-Cheat but you might be waiting a couple of days to hear back unfortunately. How would you like to proceed?
