Application: plasmashell (6.5.4)

ApplicationNotResponding [ANR]: false
Qt Version: 6.10.1
Frameworks Version: 6.21.0
Operating System: Linux 6.17.12-300.fc43.x86_64 x86_64

-- Information about the crash:
This error happens kind of randomly when booting up PC from suspension (or "hibernation"), it doesn't seem to affect anything, since I use the PC normaly after the so called crash. But, and this may or may not be correlated, the PC starts to break up into pieces and my entire screen turns black, piece by piece (background, taskbar, apps, etc), I don't know exactly if it has something to do with Plasmashell here, I'm very new into KDE Plasma.

The crash can be reproduced sometimes.

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