Fedora 29 ⏩ 30 upgrade breaks GNOME login due to incompatible extensions

After a successful offline system upgrade of a Fedora 29 , GDM cannot boot into a GNOME Wayland nor into a GNOME via Xorg session. When trying GNOME classic, it displays a distorted desktop, showing only frameless windows of tray applications.

The system is fully accessible via the framebuffer console, autoconnects to WiFi and is else up and running.

From https://fedoraproject.org/wiki/How_to_debug_Wayland_problems we learn to check that journalctl -ab registers a core dump of gnome-shell, and also few errors with custom installed extensions right before.

mv ~/.local/share/gnome-shell/extensions ~/tmp/
systemctl restart gdm

helped to restore the Wayland desktop session.
