[2020] [Crash/Freeze]Game Freeze or Crash

Hello World

I have a problem with Game Freezes and Crashs, since Update 9.0. Once it Freeze, Music is playing, can't switch to windows or Task Manager and can't close the Game. Only Shout Down helps. Sometimes it crashs hard and came back to Windows - this happens with DX11 and 12, in new Game and Lategame >60h!
My System: Win10 20H2, i7 8700K @4.8GHz, GTX 1080 Ti (every time the lastet driver Version), 32 GB RAM @3333Mhz

I reinstalled DX, the Game, checked Files from Anno, reinstalled Driver, switched between DX11/12, checked Windows Updates ...

There are no DX Errors from DX Diag. But i found this Anno logs: http://bitsicher.de/log.7z
(one LogFile is to long for Paste here completely)

There are so many Errors, is it normal? And the Freeze/Crashs takes more and more with Update 9.1

Thx for reading!
