Matter devices just stopped working

Hi all - I am a newbie to HA and been using it for the past 3 months. everything was going well until I updated to one of the recent new versions. Now it seems like a lot of my ‘Moes Matter G10 lightbulbs’ just stopped working and are unavailable.

Initially I set them all up directly through ‘add matter device’ in HA rather than initially through the Moes app, so have no other way to connect to them.

I am not sure as to how to solve this with the different lights, and why the matter integration is not working for me. Is there anyone that can give me guidance on what to check for or steps to help resolve the issue. thanks.
