JetPack 4.5 "Cheese" and "Desktop sharing" are crashing

I installed JetPack 4.5 on a Jetson nano (4 GB) and got the following issues:

When starting Cheese to verify that my Logitech C270 USB webcam is working, the app is crashing.
When starting Cheese without any USB cam connected, it is NOT crashing.

Another issue is that when i try to start “Desktop Sharing” in the “System Settings” menue it crashes too.

Can anyone help mit getting started with my jetson nano?

Can you share the dmesg when error happens?
