This is still a issue, I verified, reinstalled, rebootet - run NO mods and just want to play, wtf are there even a anti cheat feature in a non pvp game???
That link leeds to a “oops page dont exsist”
I know two instances where the only solution was a Windows reinstall. Obviously it was something else than a broken Windows, but EAC can be a little ****. Maybe https://www.resplendence.com/multimon could help you see what is happening / what files are accessed prior to the error. Just an idea, I haven’t solved anything EAC related with that, but some similarish issues yes.
Edit: their sanity check tool can also provide hints of some suspicious drivers and other stuff.
And you are still posting about it in a patch note thread.
Too bad the link broke at some point, but I’m sure you can find the tech support section if you try.
The entire link there leads to a thread; try just going to fatshark.se/support instead to submit a ticket.
Needless to say, you are a powerful necromancer.
