gdb backtrace

SUMMARY
I've just upgraded to Plasma 6.3.0, and after I rebooted my computer and auto-logged in, I noticed I had no desktop wallpaper, and the desktop's right-click menu wasn't doing anything as well.

I then checked the system logs and noticed a kwin_x11 crash there (see attachment for the gdb backtrace).

STEPS TO REPRODUCE
1. Make the X11 session the default one
2. Enable auto-login (maybe not necessary?)
3. Reboot

OBSERVED RESULT
kwin_x11 crashes, and even though its systemd service ()plasma-kwin_x11.service restarts itself successfully, you're still left with a black desktop wallpaper, and no ability to right-click on the desktop.

EXPECTED RESULT
No crash.
