Can't open Ubuntu software in Ubuntu 20.04 (ERROR: not connected to the gnome-3-38-2004 content interface)

this morning I realized that I cannot open Ubuntu Software. When I click on it the pointer indicates that is loading but the program never opens. If I run snap-store from a terminal I get (If I understand correctly Ubuntu software corresponds to the Snap store on 20.04)

ERROR: not connected to the gnome-3-38-2004 content interface.

Maybe the following could be useful

>snap version
snap    2.52.1
snapd   2.52.1
series  16
ubuntu  20.04
kernel  5.11.0-40-generic

>snap list

What could be the issue? is it that i don't have gnome-3-38-2004 on the list?

Solution 1:

I had this error too. I just uninstalled the snap store (snap remove snap-store) and reinstalled it (snap install snap-store)
