Hello All,
Thank you so much for the prompt and on target replies!!! Outstanding Community Support!
I think I can confirm @catlover was the most spot on.
I had purchased and installed AD from the Affinity web store.
OSX has been getting picky about where application data is installed/stored/edited pushing more of this into the current user’s library, avoiding the system library. If you have older installed AD before Big Sur / Catalina your user profile data install locations might be different???
From what I can tell AD does not create anything for the user in the ~Library/Containers/ folder any longer, but I did find a set of AD support files under ~Library/GroupContainers/ and from what I see it appears to be some of the software licensing / authentication files but not related to my user Assest files I was trying to get back. I did not need to copy / recover this data.
With AD closed, copying the “User” folder, newdomentpanelstate.dat, and preferences.dat files from this path in my time machine back up to my new clean mac user path, and I now have all my old custom created Asset panels back. All is well!
