New xbox controller double input over bluetooth on pc

Hi I'm using the new bluetooth model Xbox One controller but it won't connect via Bluetooth to my PC. It was working for me for quite a while and one day it lost sync, when I tried to resync it showed up as just "Input" instead of Xbox One controller
like it had before. It's done the same thing with my other Xbox One bluetooth controller

I have the same problem. I think it was caused by a controller update (version from 17.11.2021). I enjoyed the new fast switching feature between Xbox and Bluetooth devices (double click pairing button).

Switching controller between Xbox/Bluetooth devices - OK

Xbox connection - OK

Android mobile connection (bluetooth) - OK

PC Win10 USB connection - OK

PC Win10 Bluetooth connection - does not work. the pairing will be fine but controller does not work.

Xbox One S, 2pcs XboxOne controller, Windows 10 completely updated.

EDIT:

resolved issue - update Windows 10 21H2.

Hi,

this is by far the most popular post of Microsoft forums I found on this topic. I have very similar issue:

My expectation is that when turning the Xbox Elite Controller 2 on it will automatically connect to the PC over Bluetooth (if already paired), however, it doesn't work for me. Light on the controller is flashing steadily but it never connects.

Controller works fine over USB. It's displayed as "Paired" in Bluetooth & other devices.

Controller's firmware has been updated over USB using Xbox Accessories application.

What have I tried already:

1. Ensuring my Bluetooth adapter is working fine by connecting wireless headphones - it's OK. I also moved the adapter to the front of the chassie.
2. Ensuring controller's Bluetooth is working fine by connecting the controller to a MacBook.
3. Restarting PC, controller, Bluetooth services (and changing them to automatic), turning Bluetooth off & on before and during controller sync.
4. Uninstalling Bluetooth drivers, updating them via Windows, downloading new drivers from my MOBO (AsRock Z390 Pro4) manufacturer.
5. Removing the controller from Bluetooth devices and trying to pair it again - controller is visible either as "Input" or as "Xbox Elite Wireless Controller" however it takes a lot of tries to connect it as the device is not responding (controller light is
   flashing rapidly as it should in sync mode).

After successful pairing I observed the controller sometimes stays connected and works fine over Bluetooth and sometimes it just switches back to the "turn on mode" (light flashing steadily), which brings me to the beginning of this problem - controller
is paired but does not connect to PC.

if you're using it on both the PC and the Xbox, then it can use Bluetooth. The Xbox controller stores separate settings for Bluetooth and the Xbox and you can easily switch between them by double clicking the sync button

It takes a little practice to get the timing down

Update: Discovered another flaw was it not picking up trigger inputs as well when connected over bluetooth.

After looking up this additional detail to find similar issues; there's even more people who faced it and got nothing.

The strong assumption is that a firmware update made to the controller has effectively blacklisted it from recognizing third-party bluetooth adapters.

It's either that or something that's bugged the xinput or whatever else when interacting over bluetooth on W10 PCs caused by firmware updates.
