Preview/Video Playback issues after Update to 17.1

After updating from 17.0 to 17.1, I have unfortunately encountered some issues with video playback and preview of the Clips, both of which are not functioning at all. The Previews as well as the media player just display gray. There were no issues under 17.0.
Here's link to the Resolve Log & System Information.

De- and reinstalling of Resolve itself as well as the graphics card driver did not help.
I'd be really grateful for some advice.
Cheers
