Problems loading media in 17.1.1

Good Day
I'm experiencing some issues after upgrading to 17 that I did not have in 16. Basically, all media I try to import (regardless of filetype or source) cannot play back. I can see the audio waveform in the preview, but the image in the thumbnail is black and when imported to a timeline the play button turns red. This is the case with new projects as well as opening old projects. I also tried footage captured on my Ursa, as well as my Canon and some stock I downloaded.
I am brand new to editing in general and to Resolve in particular, so I would assume this is user error, however I can't seem to find any guidance on what settings to fiddle with.
Any ideas?
