All Applications are gone after updating - no Icons in the Menu + Taskbar, no Apps can be found

Man, I can’t even start the ■■■■■■■ Package Manager anymore because the association in the TaskBar does not work and I can’t find it in my Apps also. Of course the software is still there, but I can’t launch it anymore which makes them basically ueselss. Reinstalling any app? That would require to reinstall 100+ Applications including the System Apps :thinking:
