Ubuntu software causes most reboot

[Roland_Msl]

The top of Ubuntu software: All - Installed - Updates

It happens often, that when I click "Installed" or "Updated", only a blank window with a circle in the center appears.

Also when I search for a software at "All" and click on a search result, again only blank window with a circle in the center.

Until now, my only solution: reboot

Just found out a solution

kill "Gnome Software" in system monitor.
After this, the software center can be started new and works again
