Hello,
Welcome to the Microsoft Windows Community.
How are you, @Mark Fraher ? To help us provide a more accurate solution, please let us know the make and model of your computer. Also, press Win+i, go to System, and under "About" (in the "Device specifications" section), click "Copy" and paste the information here so we can analyze it. In the meantime, please press Win+i, go to Troubleshoot, select "Camera," and follow the on-screen instructions. If that doesn't work, you may need to install the camera drivers, which can be found on your computer manufacturer's support website.
Looking forward to your reply...
