Log-in via the plain "Gnome" option does successfully start a gnome-session. Extensions from 3.30 cause it to freeze, but that's a separate issue (it works if extensions are disabled).
More tests: the failure occurs when logging in with "System X11 Default"
or "Gnome Classic" selected from the gdm3 login screen.
