I installed Kubuntu 22.04, and when I switch to Wayland desktop, KDE simply crashes. Here's the report/stacktrace:

My nvidia card is: GeForce GTX 1050 Ti Mobile
I have nvidia driver 510 installed (the one installed by default)
The command:
cat /sys/module/nvidia_drm/parameters/modeset
returns Y. (It seems to be a requirement)
What else can I do to get it to work?
Why? I need it in hopes to get rid of Windows and start using my touchscreen reasonably well. Currently with X11, it seems like all taps on the screen just move the mouse cursor. Funny enough, even though KDE doesn't start with Wayland, a program that launches on startup launched, and I was able to tap on it properly.
