[2023] Easy anti-cheat crash after buying DLC

Sorry to hear this @Mafilovy,

Please try our solutions to the Untrusted System File error, here:

Let me know how this goes!

Hm okay

It’s a shot in the dark, but are you currently playing with any mods? If so, can you please try disabling these.

Ah okay! Hopefully factory nuking your system will help! Please let me know.

Interesting!
A bit late, but if it ever happens again, I have a vague memory of this being caused by having two instances of EAC active at the same time. Maybe you have/had a game that kept its anticheat or EAC open at all times by accident (it either failed to close or keeps starting on its own). So ye, if it happens again, might be worth taking a peek in task manager and seeing if something like that is happening.
