Bug 491157

Application: plasmashell (6.1.3)

Qt Version: 6.7.2
Frameworks Version: 6.4.0
Operating System: Linux 6.10.2-200.fsync.fc40.x86_64 x86_64
Windowing System: X11
Distribution: Nobara Linux 40 (KDE Plasma)
DrKonqi: 6.1.3 [CoredumpBackend]

-- Information about the crash:
This crash occurs every single time the OS is loaded from startup.
The KDE login screen loads, then flashes 3 times, but on the third time, the mouse pointer disappears and KDE crashes.
There is no taskbar at the bottom of the screen, nor am I able to see or select any icons or menus.
The Plasma KDE desktop is impossible to use like this, renders the OS inoperable.

The crash can be reproduced every time.

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