It can even happen that plasmashell crashes multiple times during startup and restarts itself. Backtrace looks like

Comment 1 Vlad Zahorodnii 2020-09-21 07:55:54 UTC 
It's either a bug in NVIDIA's libraries or QtWaylandClient.
Comment 2 David Edmundson 2020-09-21 08:42:04 UTC 
What Qt?
Comment 3 David Redondo 2020-09-21 08:42:47 UTC 
5.15.0
Comment 4 Vlad Zahorodnii 2021-10-13 13:32:33 UTC 
We didn't receive any new related bug reports and I didn't see any crashes at startup last time I tried plasma wayland session with nvidia. Marking as RESOLVED WORKSFORME. Either way, the crash is in libnvidia-egl-wayland.
