Adobe Rush crashs in Media selction on Windows 11

We have a new Lenovo P16 ThinkPad with an Intel Ultra 7 155H and an NVIDIA RTX 1000 Ada.

Rush can start normally, and you can click create a new project. As soon as an MP4 file is in the preview of the media selection menu (the Explore looking like window), it freezes and crashes.
Also, in Premiere Pro there seem to be some issues with lags or bad performance.

So far I have updated to the latest NVIDIA Studio Drivers.

Adobe Cloud and Adobe Apps are also updated.

I also tried reinstalling.

In NVIDIA and Windows settings, I chose the NVIDIA GPU for Rush.

So far, nothing helped.
Maybe somebody can relate and give me a hint on what to try next...
