This is terribly frustrating, this is the third time this has occurred in the last couple months, and every time it is due to an update from Microsoft. I have fixed it two previous times by removing biometric windows hello feature, re-adding, and re-installing camera drivers. However, this time it's not working, and obviously many others are affected by this. I've tried the policy manager, everything for biometrics is good to go, looked over the corresponding registry keys, removed device and drivers for anything connected to the camera, ensured that only the admin account is and work account is removed when making changes. Nothing is working.
This also affects many other camera apps and my video conference software. I love windows but this is becoming too ridiculous, if there isn't a fix for this within the next 48hrs our research team is switching to Mac. Not having Windows Hello is no big deal, but this affects other software and it's not a one time thing.
Great update :(
