Product: plasmashell
Version: 5.23.3
Platform: Debian unstable
OS: Linux
Status: REPORTED

plasmashell output
SUMMARY
The plasmashell process hangs forever on Wayland, resulting in a black screen.
Programs can still be launched using key bindings and KWin seems to be working
correctly. Killing plasmashell and running it again doesn't help.
X11 session works normally.
STEPS TO REPRODUCE
1. Install the 'plasma-workspace-wayland' package.
2. Restart SDDM.
3. Login into the Wayland session.
OBSERVED RESULT
Black screen.
EXPECTED RESULT
Plasma desktop.

ADDITIONAL INFORMATION
This only happens on my machine with Nvidia proprietary drivers, it doesn't
happen on another machine with Intel iGPU.
Wayland session worked (badly, but at all) on this machine before. I believe it
broke after the upgrade to 5.23.
Also tested on the stock Debian kernel (linux-image-5.15.0-1-amd64).
Attached: the output of plasmashell launched after killing the original process
started by SDDM, hopefully it contains some useful information.
