I see you play on an online official.
You get the same random error if you try to run a SP/Coop game?
Or also, the same error if you try to play on another server online?

In your shoes, i will try to run a SP/Coop game first, play some time and see what’s happens.

Both game istances (and any other server game you start) SHOULD be separated one by the other, but honestly, i don’t play on officials, just SP/Coop, so before doing this, do a search on the forum about, i don’t want to suggest something can be detrimental for you.

Running a SP/Coop should be useful to understand if you get the same issue or not.
If you get the same error, then maybe can be something related to your pc, hard to define, because as you said, drivers are updated.
If you don’t, the problem can be just on this specific server.
