'Ubuntu Software' app not loading on 22.04

I see previous questions about this but none of the answers work and it has been suggested that it is a problem at 'Snapcraft'

If this is still a problem it is a pretty poor show - is there an alternative GUI for managing installed software (I am trying to uninstall something)?

When I click the icon I get a spinning wheel cursor pointer for about 10 secs and then it goes back to nornal and nothing happens. No relevant process is running.

/var/log/syslog shows this every time I try.

What does this mean please and how do I fix it?This is 22.04.1 updated from 20.04 which was updated from 18.04. There were also some automatic system updates earlier today.

Any suggestions, anyone else got a problem with the 'Ubuntu Software' app?
