GNOME Contacts attempts to load multiple gtk versions
Updated my systemd to 42.alpha, gnome contacts on my user account crashes with
(gnome-contacts:6074): Gtk-ERROR **: 16:31:08.237: GTK 2/3 symbols detected. Using GTK 2/3 and GTK 4 in the same process is not supported
gnome-contacts works on a clean/unconfigured live system (in evolution I see my local/personal addressbook plus two addressbooks coming from my nextcloud instance)
