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

Hello,

I'm your Independent Advisor for today. Let's work together and arrive at a solution.

Please download the update manually from the link below. Make sure you select the one being installed the last time:

You can also follow the steps in the link below to attempt repairs:

If the above doesn't work, you can do a repair install of Windows 10 without affecting your files and apps:

1. Download and create your Windows 10 ISO by clicking "Download Tool Now" and following the steps in this link:

2. Locate and right-click the ISO file, then click "Mount".

3. Go to File Explorer and open the virtual drive where the ISO is mounted. It's usually labeled "ESD-ISO".

4. Open setup.exe and follow the on-screen steps.

This repair process might take a while. Once it's completed, try installing the update again through Windows Updates and see if it will push through.

Hope this helps.
