Hello Roland,It's been a while, but it took some time for me to get to the conclusion that I could not solve this. I eventually chose to switch to SDDM. This solved all issues. Autologin worked and I could login with Wayland without getting thrown back to the login screen.
I'll add my log files if you are interested. Regards, Arjen
