I want to add to comments from garthoid about AppleID problems.
I ran into problems with errors/warnings disappearing after updating to Xcode 14.3.1 (sorry don't remember previous version I was using).
In my case, I had a company ID (personal LLC company - sole developer) that Xcode said had exprired and needed to log in. I don't really remember when/how this ID was created, but there really is no associated login with Apple for it that I am aware of. I deleted the ID. The company is still listed under "Team" on the Accounts tab.
However, after deleting that ID, Live Issues started working again.
Hope this can be helpful to someone else.
