For some reason after a MacOS "upgrade" to 10.15 Catalina the Bluetooth Appears "Permanently" Not Available? How can I diagnose which “a device” to connect to get Bluetooth to work ?

Upgraded to 10.15.2 but no better.

bluetooth wireless settings

taskbar

not available

os version and hardware

Any suggestions? Does this have anything to do with Bluetooth pan internet sharing?
