HD User facing webcam on ConceptD CN517-71P not working after windows update

Myt builtin webcam is no longer working on my ConceptD CN517-71P after a updated my Windows. Current environment
Edition Windows 10 Pro
Version 20H2
OS build 19042.964
Experience Windows Feature Experience Pack 120.2212.2020.0
I've restored Windows to the factory settings and then it works fine. When I uninstall the driver and reboot Windows recognizes it but something goes wrong with the install of the usbvideo service. I've looked at all recommendations of Windows support & I've tried other driver utilities but no luck so far. Any ideas?
