Random Crashes every few minutes

Hello everyone!

I have been trying to play for 3 days now, but my game keeps crashing every few minutes or directly on startup.
Most often it is one of these errors:



Other times the game just freezes and stops responding:


Other times the game just closes without any message.

These are some examples from my client log file:

"

I used to play over steam, but after reinstalling there didn't work I switched to the standalone client. That keeps crahing too though. I already reinstalled that one and ran multiple packchecks with no positive results (even though it did say "repaired" the first time it ran). None of the common fixes worked for me.
Installing on HDD vs SSD also made no differences.
Graphics drivers are up to date, windows updates are all installed.
I couldn't find any difference when trying different ingame settings.

My specs:
Win 10 Home
i7-10700k 3.8GHz
32 GB GSkill Trident Z RGB
RTX 3080 Zotac
Samsung SSD 970 EVO Plus

Any kind of help would be greatly appreciated.

Best regards
