-- Information about the crash:
- What I was doing when the application crashed and unusual behavior I noticed:
Before I created new sessions and switch to it and switched back -> kwin crashes
After a reboot -> sddm showed login animation -> resettet
after deleting .local folder -> sddm could log me in -> this crash occured after some time

The crash can be reproduced every time.
