I fully agree, unfortunately 4v4 games are a rarity nowadys

So I have finally found the issue and would like to share the cause:
I use a KVM switch for my 2 displays. Now I have bypassed my main display (have it directly connected) and the crashes are gone.

Sometimes my KVM switch would drop the displayport connection and I have to switch it back and forth. It seems that this dp drop caused the crashes

Did everything multiple times. Keeps crashing
Can a KVM switch have something to do with it?

@magge
Thank you for your help.
I deactivated UIparty and it feels like the crashes are much less often. Still crashes though.

I enabled the debugger and got a way more comprehensive log.
Can someone please take a look at it? Would be greatly appreciated!

Hey guys,

please I really need your help. Since a couple of weeks my game keeps crashing after a while. But only sometimes. I have reinstalled everything, deactivated my mods, disabled audio devices, installed java runtime environment.
This is so frustrating to experience besides all the ddos stuff, disconnects, finding a game at all...
This is a the last log:
