That exactly what I meant.
When you were on xorg (with
WaylandEnable=false) the Gnome option under the wheel(gear) corresponds to Xorg, when you change to
WaylandEnable=true Gnome corresponds to gnome on wayland and the Gnome on Xorg to xorg.
but after the change (at least in my case) although the Gnome option was the first one it logged in to xorg and after logging out and manually selecting the Gnome version it logged in on wayland. and afterwards it automatically logs in into wayland (already 1-2 days, with numerous restarts).
so yeah, if it fails to login, that could be there is a problem with wayland on your machine and it fails to initiate and reverts back to xorg. I can’t help much on this topic, maybe you can try to gnome classic as well, just to be sure that it can select the sessions and maybe try different kernel, Idk.
