I have not experienced this and no direct solution. You should probably check your logs to see what's wrong. So on boot, try to log in into Wayland, then open up a shell and run these to see which errors pop up.
journalctl -b | grep wayland
journalctl -b | grep gnome
journalctl -b | grep gdm
# and for more general errors
journalctl -b -p 3
