Random Fatal Error Crashes

[DesertFox]

So since I started playing the game a week ago I had these random crashes in 3 to 4 hour Intervalls, however now i get them like every 10 Minutes. In fights, on the continent, cutscenes, it is basically unplayable. Anyone please know a fix for that? I already tried:
Verify game files
dx11
Running as admin
Checking my drivers
aloowing it past firewall

Would be so thankful for help.
