Nautilus does not open folders on desktop
Steps to reproduce
Double click on a folder on desktop does nothing. I can open the folder only using the "Open with" menu.
Reproducible in: Ubuntu 18.04
Additional information
I tried all the possible solutions that I found around, with no success. If I kill nautilus-desktop and restart it I get the following message:
(nautilus-desktop:2256): Gtk-WARNING **: 12:02:46.328: Failed to register client: GDBus.Error:org.gnome.SessionManager.AlreadyRegistered: Unable to register client

Please ask your system administrator to enable user sharing.
And if I try to open the folder:
