Windows 10: Windows Hello Face Windows Hello Fingerprint Windows Hello PIN didn't work on my win10

I can't setup any of Windows Hello Face, Windows Hello Fingerprint or Windows Hello PIN, But my devices seem proper installed. how can i fix this?

Windows Hello Face/Fingerprint

The Windows Hello Face/Fingerprint feature was working on my HP Envy and now it is not working and it says that my laptop camera/fingerprint scanner is not compatible, when it was working less than 12 hours ago. When I look into how to reconnect or find
Window Hello Fingerprint/Face biometrics the only help I get is to the Windows 10 sign-in options.
I need to know how and were to find the Windows Hello Face/fingerprint biometrics management settings that is not in the sign-in options, but is how to re-download it or check it's compatibility status with my laptop.

 

Windows Hello Face stopped working

After installing Windows 10 1909 Update KB4551762 and restarting my M/S Surface Book 2 the Windows Hello Face login would not work. I logged on with my PIN, went to settings/accounts to check my Hello/Face Sign In. Message advises that Windows could not find a camera compatible with Windows Hello Face. Prior to the Update Windows Hello Face was working. Would appreciate any feedback on how to resolve this issue

 

Windows Hello - PIN and Fingerprint not working anymore

First, this is similar with
this question, but that thread is locked with no solution.

After some months of fingerprint login working fine, after some update few months ago fingerprint stopped working, error message like "windows hello encountered a problem and stopped working".

- noticed that PIN is not set up anymore

- tried to set up PIN or fingerprint - not working (fingerprint sensor was not even recognized by Hello, even though Dell tools verification was ok).

- reinstalled fingerprint sensor driver, managed to determine Hello to find sensor and allowed to set up fingerprint until near the end when it requested for a PIN to be setup. asked for my password but the next screen (to enter PIN twice) never appears

- deleted Ngc folder, recreated, managed to set up PIN individually

- when I try to set up fingerprint click on Get Started, asks for PIN, and after I enter the PIN the popup disappear but does't go to the next step with sensor, stays there with only the Cancel button visible.

To answer obvious questions:

- windows updates done. no change

- new account created and tried to set up. same issues with fingerprint setup, at the end not setting up PIN or I set up PIN separately on fingerprint start does not go further than entering PIN after Get Started.
