Windows 20H2 update seems to have broken Windows Hello Face Recognition

With the recent update to Windows 20H2 (version 19042.572), the Windows Hello no longer works with the Logitech BRIO 4K camera. I have uninstalled and reinstalled the drivers, disabled and re-enabled Windows Hello. The BRIO works fine with Teams, Skype, Windows Camera, Logitech Capture, and Logitech Camera Settings. The problem ONLY occurs with Windows Hello. It had worked fine for years prior to the 20H2 update.

Also, Windows Hello works fine with the fine with PIN and with my fingerprint scanner. Only facial recognition is now broken.

So BRIO works with apps other than Hello and Hello works fine with everything but facial recognition via the BRIO 4K, but the combination of BRIO + Windows Hello broke with the latest Windows update.

Is this working for anyone with the same configuration?

The error message Windows Hello gives is, "Sorry something went wrong. Camera is currently in use by another app. Close the app and try again." But nothing else is using the camera (proven by the fact that all the apps listed above will launch and use the camera just fine).

One other note, which may be helpful diagnostically: when Hello is trying to scan for my face, the red light on the BRIO does flash for several seconds as if it's working, but no picture ever comes through. There is obviously at least some successful communication between Hello and the BRIO.

I also tried plugging the BRIO both directly into different USB ports on the computer and into various hubs. Always got exactly the same results.

Any suggestions? Do we need to wait for a patch from MS to fix this defect in 20H2?

Thanks,

Colin

    I found the problem for me. Closing the laptop lid made the brio not work. Leaving the lid open fixed the issue. Not ideally the best solution, but it's better than nothing.

    I had a peak on this in a debugger (Since I have the same camera, and suffers from the same problem.)

    It seem like there is a race condition // dangling handle error in WINBIOSTORAGEADAPTER.DLL.

    The process is crashing due to UnlockFileEx throwing an INVALID_HANDLE exception.

    And the reason for this is that the file handle passed to UnlockFileEx has been closed already by another thread. - So the handle is accessed after closure.

    So.. We need Microsoft - to investigate this since it's their module.

    In case people following this thread have not noticed yet, the latest Windows update fixed this issue, at least on my Surface Book 3 Business (update also contained several firmware updates).

    My Logitech Brio camera now unlocks the computer upon facial recognition.

    Per Larsson, as there have been a few different issues raised here, which one is this? Does this align with the message when trying to set up the BRIO for Hello "Sorry, something went wrong. Camera is currently in use by another app. Close the app and try again." (when it's obviously not in use, as easily proven by the fact that it works with any other app started after this and by the fact that the attempt to set up Hello does turn on the camera red light) or one of the other reported problems using Brio 4k with Hello?

    Currently, my hope is that a new install of the upcoming Windows 11 or the new Dell 4k camera will resolve the problem. I have lost any hope of the BRIO working on my desktop PC with Windows 10 Hello. I currently use a fingerprint reader with Hello, which is not as convenient as when the BRIO worked for Face Recognition, but it's not too bad. And the BRIO still works fine for everything else, just not with Hello.
