- Run the Bluetooth troubleshooter at Settings > System > Troubleshooters > All Troubleshooters.
- Try Updating the Bluetooth driver from the PC maker's Support Downloads webpage for your exact model. Install it even if it's the same or newer than the one in Device Manager reached by right clicking the Start button. While there check that you also have the latest chipset, BIOS, display, network, USB and all other drivers, compared to the ones presently installe
Right click Start button to access Device Manager, locate Bluetooth device (if necessary from View tab Show Hidden Devices), on Driver tab see if Roll Back is available, if not try Update Driver, first automatically, then Browse, then Let Me Pick to try all previously installed Drivers.
If these fail Uninstall the Driver, restart PC to reinstall. If the BT driver is not there, access the View tab in Device Manager to "Show Hidden Devices."
- Make sure you're pairing correctly as shown here: https://support.microsoft.com/en-us/help/15290/...
- If you think the BT adapter has failed, you can replace it easily with a USB nano adapter like this one: https://www.amazon.com/ZEXMTE-Bluetooth-Receive...?
- Establish a Clean Boot to see if that resolves it:

- Run the System File Checker/DISM in WIndows 11:

- If that doesn't fix it then you can do a Windows 11 Repair Upgrade which reinstalls Windows while saving your files and apps in place, brings it up to the latest version by the most stable method, takes about an hour and resolves most problems: https://www.elevenforum.com/t/repair-install-wi...
Feel free to ask back any questions. If you'll report back results for each step in each link it can help determine what else needs to be tried. I will stick with you until it is fixed.
