It takes a while to get around to all apps and this morning I encountered an old Apple App that no longer works, "Airport Utility". It launches normally, reads all the settings and everything works until I tried to make a change when it reported an internal error and unable to complete. I knew it was coming but I am tempted to pay taps for an old friend of many years -- My Apple Router
I just got this error message in Catalina when I tried to change my band from 5 GHz to 2.4 GHz and again when I tried to change my AirPort Express Base Station password. (I can't begin to remember the last time I tried to change anything in AU, but the error message is definitely a new thing.)
Is it the same error you're seeing?
I use my Verizon router for Internet, so I don't mind not being able to change my settings as long as AirPlay continues to work.
(I've got no idea in which thread it was, but we touched on this subject a while ago.)
