Can't turn on Bluetooth, Bluetooth adapter disappeared both in Device Manager and the Hidden Devices in Device Manager

Hi all,

My PC has been working fine before, but decided to act up today. Out of a sudden, my bluetooth is turned off, and there is no option to turn it back on. I tried reinstalling the drivers, remove, and repair, but it did not help. 

The Bluetooth Adapter is still not showing up in my Device Manager, even when I select to show Hidden Devices.

Now I am stuck, unable to connect to my speakers, controllers, and keyboard. Gotta quickly find a wired keyboard just to type this. On a side note, WiFi is working fine too.

Mainboard is a Gigabyte Aorus B550i, installed both bluetooth drivers from Gigabyte and from Intel, didn't help. Bluetooth adapter is an Intel Wi-Fi 6 AX200.

Please help :(

    I'm only saying cause something (likely the downgrade in BIOS) fixed mine and it's been working for over a month now or longer can't remember. 

    I'd rather try than yank out your motherboard and live without your PC for quite awhile.

    Thank you. This just saved me from a low Wife Acceptance Factor for the new build. (GB B550i AX Pro here). 

    She kept telling me she couldn't see any of her Cameo (vinyl cutters) anymore and Bluetooth was just gone, and until I had a chance to look at it today I didn't quite believe her.  But after the ratrace of not even finding the hidden devices, re-running the downloads from the manufacturer all acting like the module didn't even exist, I was tearing my (nonexistent) hair out.

    Any idea what makes the module just drop out? Static shock or overheating putting it into a shutdown protect mode and never coming back on its own?  (As with others here, the Wifi never stopped working....)  EDIT - never mind, reading on about the power settings....

    Unfortunately my good luck lasted only a few days and the device has dissappeared again. The usual power off, unplug, drain the power by trying to turn on, then turn on and restart works ok.

    This problem seems related to dropping into and out of standby. I have never lost the device whilst the PC is operating. Also, I never fully shutdown the PC so I don't think it is related to the full power off sequence.

    Given that this issue occurs on different motherboards from different manufacturers, and that Intel hints at an issue with the device with standby, I suspect this is an Intel driver or hardware issue.

    What can be done to get this properly fixed, otherwise, this amounts to selling a defective product and there should be some consumer remedies (depending on your jurisdiction of course).

    So whatever I have done (maybe the flash back to an older BIOS F2) recently seems to have fixed my Bluetooth issue permanently. It's odd though I was running an older BIOS and it didn't work however now it's fixed. I have the Gigabyte B550I (mini ITX) Aorus Pro AX rev.1.0 motherboard and did have a Beta Bios which has since been removed from Gigabytes BIOS files and somehow I think that was the cause. Regardless I've been running glitch free now for a couple weeks. 

    thank  you 

    happy new  new yer

    I noticed that the latest Intel Bluetooth driver has the following comment 'On some systems, Bluetooth device may show a yellow bang in Device Manager after rebooting or resuming from Sleep/ Hibernation mode.' The release notes are here 

    ReleaseNotes_BT_22.10.0.pdf (intel.com)

    I installed this but the Bluetooth hardware still disappeared. However, I had previously disabled a setting in Device Manager on the USB Root Hub to which the Bluetooth device was attached.  I reenabled the setting 'Allow the computer to turn off this device to save power' on the USB Root Hub. With the latest Intel driver I have not had any failures since but it has only been a few days.
