-- Information about the crash:
Plasmashell crash at restore from lock screen.
I am use KVM switch, so probably crash is related to it.
Crash not happening on each lock/unlock, but anyway happens quite often - few times per day.
It definitely related to fedora 40 upgrade - crash does not happen on F39.

The crash can be reproduced sometimes.
