I've the same issue with my XPS 13 9343 Notebook after updating from Plasma 5.27.10 to 6.0.1. Same steps, same result - can't login using wayland (will return to SDDM after display a black screen with a prompt for about 10s), only X11 is working. Uploaded my journal log from startup until login attempt using wayland.

This is crashing within your graphic driver. Please report to Mesa
Thanks David, I've fixed the issue by switching from "mesa-amber" to "mesa", which will use "iris_dri.so" instead of "i965_dri.so". This should work for you Christoph, too. You can try "iris" by using the following command: MESA_LOADER_DRIVER_OVERRIDE=iris glxgears (make sure you have "mesa" package installed), in case you can see the spinning gears and no error get reported in console iris should work for you, too.
Switching to "mesa" (instead of "mesa-amber") and using iris instead of i965 actually works. My previous attempts to switch, already some while ago, had not been successful. I now realized that I also had to remove the old xf86-video-intel package in order for SDDM to start up properly.
