After I upgraded from 20.04 to 22.04.1 I don't see any icons in Ubuntu's dock. There is only the 9-dot-icon, which opens the applications overview. Even if I try to add an application manually ("add to favourites") the dock stays empty.
What could be the reason? And how can I fix it?
This is how the dock appears at the moment:
edit: I noticed, that the dock icons are present, when I log in with "Gnome" or "Gnome with Xorg", but not with one of the "Ubuntu" options.
