Application: plasmashell (5.23.5)

Qt Version: 5.15.3
Frameworks Version: 5.90.0
Operating System: Linux 5.13.0-28-generic x86_64
Windowing System: Wayland
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

Just log in.

There is just blank screen with wallpaper and  nothing more. I can however run programs through ALT+F2 and it is possible to switch between them by ALT+TAB.

If I try to restart plasma like this:
ALT+F2 > killall plasmashell
ALT+F2 > kstart5 plasmashell
It won't help. It crashes immediately again and again.

It all started after some update by Discover.
