Garmin 955 not visible to a Windows 11 Pro PC via Bluetooth

My Garmin 955 is no longer visible to send my HR data to my PC. I've restarted Garmin 955 multiple time and the Windows 11 Pro PC. 

Apple IOS devices can see and connect but not the Windows PC but it has worked before and also worked with a 945 I upgraded from so it must be the 955 update.

Is there a patch coming for v20.29 of the Garmin software ? 

best regards
