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
