Qt Version: 5.15.10
Frameworks Version: 5.109.0
Operating System: Linux 6.4.12-zen1-1-zen x86_64
Windowing System: X11

-- Information about the crash:
Plasma shell hung up after turning on large docker containers. 
The KDE system itself hung up, controls and other little-important widgets suspended work.

And after run: plasmashell --replace 2> /dev/null  &

And then I had to restart the plasmoids, it helped temporarily.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
