Premiere doesn't work anymore after major PC upgrade

[weid]

I upgraded to a new CPU and had to upgrade the Motherboard for it as well.

I had to re-login to cc, but everything works fine but premiere (like every single app on the pc, not only adobe)

Premiere can't read videos anymore, it shows a grey screen, no movement, or "pending media". I recognized that in some projects it searches for missing footage on drive-letters that never existed (like h or i).
Also, it doesn't shut down properly and makes the whole os behaving weird until it's forced shut down with the task manager.

I tried multiple complete new installations (with purging all user data on deinstallation) as well as removing everything from the media cache folder.

Is there something else I could try? I don't want to do a complete windows reinstall only because premiere behaves odd.

ty!

Thanks for your help offer. While making a short screen capture to record the behavior of that error, I figured out that my two-screens workspace caused it. I deleted that workspace and set it up anew. Now everything is running again. Sorry for the inconvenience, this can be closed or deleted.
