I can't say how it happened as I regularly used my air-pods to enjoy music via the Bluetooth connection, and then one time I could no longer connect. The Bluetooth switch had disappeared, along with the icons etc. I checked in the Device manager and it was nowhere to be seen except under the "hidden devices" within the "View" heading. This happened once a few years ago and I do not remember how I retreived it, but it was done through the "Hidden Devices" tab.I have tried to use the Bluetooth troubleshooter, but it has not been of any help. Any ideas out there?
