I found the problem in the Digital Well Being and Parental Controls section of Settings. Bedtime mode had been turned on and triggered.
I have NEVER even gone in there or turned anything on. Something in beta 4 seems to have activated it and something triggered it on this morning.
I did file feedback along with a log so I’ll be anxious to see if I hear anything back from the beta developer group. I’m also anxious to see iff this happens to anyone else. I know I’m not the first as a search on duckduckgo came up with an article on the problem and the solution.
