I’m experiencing exactly the same issue described in the thread linked above.
In my case, the steps suggested in point 1 did not help. There actually was a problem with the Bluetooth User Support Service, but fixing it didn’t resolve the underlying issue. The Bluetooth Troubleshooter from point 2 also didn’t work — the window would freeze during startup. I was only able to launch the troubleshooter after manually enabling several related services, but then it froze again during the “detecting radio” stage.
I also tried uninstalling all Bluetooth-related devices and drivers, including the Wi-Fi/Bluetooth card drivers (I’m using a Realtek RTL8852BE WiFi 6 802.11ax PCIe Adapter). Interestingly, even after removing every Bluetooth driver (paired devices and the adapter itself), my Bluetooth mouse (Logitech MX Master 2S, connected via Bluetooth only, not via Unifying dongle) continued to work — which makes the situation even more confusing.
System file and health checks did not help either (sfc /scannow, DISM /CheckHealth, /ScanHealth, /RestoreHealth). Eventually, I performed an in-place reinstall of Windows 11 using a local ISO. After that, I can launch the Bluetooth troubleshooter, but it now hangs on the prompt “Do we have your permission to run automatic diagnostics to resolve Bluetooth issues?”
At this point the Bluetooth behavior is back to where it started:
If any Bluetooth device appears in the list, it is only one of them (mouse or headphones), even though both are connected and working.
If I exit the Settings page and return, the list becomes completely empty — no Bluetooth devices are shown at all — despite them still functioning normally in the background.
All of this makes the Bluetooth subsystem behave in a completely unpredictable and seemingly inconsistent way.
