Bug 462765

Application: plasmashell (5.26.4)

Qt Version: 5.15.7
Frameworks Version: 5.100.0
Operating System: Linux 6.0.11-200.fc36.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 36 (Workstation Edition)
DrKonqi: 5.26.4 [KCrashBackend]

-- Information about the crash:
Plasmashell in kde crashes randomly. No specific reason can not be found. I have tried doing the last thing that i was doing before the crash but it didnt work, I have failed to spot a reason why it crashes

I am using:
	GPU: Nvidia GTX 1660 super (proprietary nvidia driver)
	CPU: Ryzen 7 3700x
	Distro: Fedora 36
	Theme: Fluent rounded
	Icons: Kora
	Package Manager Kde is installed through: dnf
	
This started happening after the last system update

The reporter is unsure if this crash is reproducible.

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