Application: plasmashell (6.1.2)

Qt Version: 6.7.0
Frameworks Version: 6.4.0
Operating System: Linux 5.15.0-116-generic x86_64
Windowing System: X11
Distribution: KDE neon 6.0
DrKonqi: 6.1.2 [CoredumpBackend]

-- Information about the crash:
This started happening after the update to KDE 6.1.

I switched to an x11-session, because screen sharing
in MS Teams, is simply not working with wayland, after
the update to 6.1

Since then, every time I turn off my monitor, and
then turn it on again, plasmashell crashes.

That's pretty much it. If I let my monitor "sleep",
and "wake it up" again, this does not happen.

This is extremely annoying... :(

The crash can be reproduced every time.
