Windows 10: My Bluetooth Randomly Disappeared and Stopped Working

One day my Bluetooth randomly stopped working and disappeared. If I try to connect a Bluetooth device, it instantly says "Couldn't Connect", the Bluetooth troubleshooter says that my device doesn't have Bluetooth when I know it does and my BIOS says that Bluetooth is installed, and I checked my drivers and I didn't see a driver for Bluetooth. I tried installing Bluetooth drivers from my laptop manufacturer's official website and still had no luck. Can anyone please help me resolve this issue? Thank you! My Laptop: Dell Inspiron 15 3511 with Windows 11 Home, Version 22H2

audio randomly stops working

Hello all,

My computer is currently connected to my Vizio E420-A0 TV (HDMI). My audio randomly stops working and the display audio device disappears. When it works I can see it in device manager:








And when it stops working it disappears:





The driver seems to be up to date:





Disconnecting and reconnecting the cable doesn't help or turning the TV off and on, but rebooting fixes it. Any ideas?

 

No bluetooth after system restore

Thank you for your reply.

I mean I have used a Windows system restore point. I tried restoring bluetooth with commands in CMD (sfc/scannow; DISM /Online.....) and by updating and uninstalling devices in the device manager. Update did not work. Uninstalling bluetooth devices made Bluetooth disappear out of the hidden devices list.
All my steps I took worked but did not change anything in my bluetooth device list.

I am using the bluetooth of my mainboard. MSI Z370M Gaming Pro AC
My guess would be, that disabling the bluetooth network adapter before using a system restore point, disabled Bluetooth after using the system restore point.

In the device manager I get this message in the USB Device list for a unknown USB Device:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.

 

Bluetooth stops working on windows 10

The bluetooth on my laptop randomly stops working.

While I'm using my bluetooth mouse it gets disconnected.

When I open the bluetooth page in settings the toggle ON OFF switch disappears.

When I click 'add bluetooth or other advice' in the settings it says 'Couldn't connect... try turning on bluetooth on this device' (How??)

There's no bluetooth icon in the action centre.

This has happened multiple times. After a while it randomly connects again and the bluetooth ON OFF switch returns to the settings page.

This is incredibly frustrating as there is no option to do anything when this happens and I just have to wait.
