-- Information about the crash:
- What I was doing when the application crashed:
I installed new opensuse tumbleweed snapshot with kde update to 5.70.0

After the first reboot plasma crashed. I see short the desktop with taskbars then I see a black screen.

After each boot now plasma crashes and my system is dead.
.

The crash can be reproduced every time.
