Hi there,
Can you try to update all the drivers especially updates that are applicable for Windows 11 from your device website. Also update the BIOS as it seems for many users updating these has sorted the Bluetooth issues in Windows 11.
The below thread discusses the same issue and you can try out some troubleshooting steps from this and see if that helps you to sort the Issue. WIFI and Bluetooth Connection are gone after Windows 11 Update
I hope this information helps. If you have any questions please let me know and I will be glad to help you out.
