Installed Kubuntu upgrade version 21.10, then tried to login to Plasma-Wayland desktop.
Looks like it's crashing in the Nouveau graphics drivers for your NVIDIA GPU. Can you please report it to the Nouveau developers? See https://nouveau.freedesktop.org/Bugs.html Thanks!
Created attachment 143305 [details] New crash information added by DrKonqi plasmashell (5.22.90) using Qt 5.15.2 - What I was doing when the application crashed: Loggined into Kubuntu 21.10 desktop with Plasma Wayland - Unusual behavior I noticed: I saw wallpaper, which was turned to black screen after few seconds.
