This is a well-known issue. If you refer to the Launchpad Page of Ubuntu Software, you'll see a handful of bug reports regarding the same with no answers from the developers. As a result, in Jammy 22.04, they've chosen to use Gnome software instead. Gnome software is working fine without any issues. You can install gnome-software using:
$ sudo apt update
$ sudo apt install gnome-software
If you want to remove the Ubuntu software app:
$ sudo snap remove snap-store
Gnome software is way better than the default application centre. The user interface is nearly the same.
Note: Ubuntu Snap Store is a re-designed version of Gnome-Software but unfortunately with bugs.
You can launch gnome software using:
$ gnome-software
You can also launch it using the application overview.
Here is how it looks like:
Here is the UI of Gnome Software in Ubuntu 21.10:
You can install additional plugins for it too. For example, you can run the following command to enable the snap
plugin in Gnome Software:
$ sudo apt update
$ sudo apt install gnome-software-plugin-snap
If you want to enable flatpak support then you can run:
$ sudo apt update
$ sudo apt install gnome-software-plugin-flatpak
