GNOME on Xorg login session gives black screen and X cursor

When I login with a “Gnome on Xorg” session I get a black screen with an “X” cursor but nothing else. I dont have a desktop after that point. Im on Fedora 39 with an updated system.

The only way Ive found to switch display servers is editing /etc/gdm/custom.conf
and uncomment the respective line. But I still dont know why the original method I described does not work.
