Installed Kubuntu upgrade version 21.10, then tried to login to Plasma-Wayland desktop.
Comment 2 Nate Graham 2021-10-20 14:57:50 UTC 
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!
