Resolve crashes over and over

Hi there,

i'm new in Resolve and video editing.
I just upgraded my PC also because of Resolve.
The file import works fine as well working with nodes in the color tab.
But as soon as i start working with windows, Resolve crashes out of nothing.

I can always restart Resolve after a crash but then it crashes over and over again.

My setup:
Resolve 15.3.0.008
AMD Ryzen 5 2600
Asus Prime B450 Plus MB
32GB Ram
Asus Arez Radeon RX580 8GB

here is the link to the log-zip and nfo file dropbox.com/sh/56rxw6r0qrwjq2e/AADueaYP6Ule1h0yHb9cCnUea?dl=0

I hope, you can help !!!

Thanks a lot !!!
