Hello, Christopher R Flint
Welcome to Microsoft Q&A Community.
Settings stalling is usually caused by outdated or corrupted camera drivers and outdated firmware, both of which can be resolved by reinstalling the drivers in Device Manager and installing any available firmware updates. Ensure that Windows Biometric Services are enabled and checking the Camera Privacy Settings under Settings > Privacy and Security > Camera Allows Windows Hello access is a key prerequisite, as shown in the figure:
At the same time, Enable Windows Biometric Services Open the service (services.msc) and verify that the Windows Biometric Service is set to manual (trigger startup) or automatically and is running

If the problem still exists after trying the above steps, please share with me your PC model. And the model of your webcam? So that we can do further investigation.
