Glad to hear things are running a little smoother for you. The disappearing AC thing is something tech is aware of. Currently the fix is running a repair as you have done. Not sure if this is related to Windows 11 or not.
I know our upcoming version, V11.2, has been tested on Windows 11 and it works. That should be coming out soon.... and has a lot of other really awesome features that should get the users excited. I don't know how much I can say without getting into trouble with Chris Conrad, but its going to be a good release. Some the features were even recommended by the UBB (that's all I am saying for now).
I'll post details once I get the ok.
