gnome-software hangs, refusing to start from background
The same symptoms as with #1091 (closed), but in my case it was not fixed by updating to GNOME 40.
Some time after being started in the session (?), the Software application cannot be brought up using the launcher and the process has to be killed.
Currently on Fedora 34, package gnome-software-40.1-2.fc34.x86_64
