Hello Brian_Ung,
I'm John an Independent Advisor and a Microsoft user like you. I want to apologize if you encountered this issue. I understand you have a problem with your laptop camera. What is the make and model of your device?
Some laptops have a privacy switch or a camera shutter key that can be used to turn off your webcam and prevent it from being used.
Camera Privacy Switch located at the right side of the laptop
Camera Shutter Key located on the keyboard
Please try to press FN+F6 or CTRL+F8, F10. or try other F key combinations.
Open Device Manager > Under View tab > Show hidden devices
Expand Camera > Check if you can see your camera device
Please try to check this support article if it helps

You may also consider to Perform a System Restore on an earlier date which the camera was still working fine.
Press Start
Search for Create a restore point, and click the top result to open the System Properties.
Click the System Restore button.
Choose a different restore point. Click the Next button.
Select the restore point that you want to use on your computer. You can check the box "Show more restore points"
Click Next then Finish
Kindly let me know if this helps or if you have any further concerns.
Sincerely
John DeV
Independent Advisor
