You might need to give apps permission to use the camera. In newer versions of Windows 10, some apps don’t have default access to the camera.
To let your device access the camera, select Start , then select Settings > Privacy > Camera . In Allow access to the camera on this device, if Camera access for this device is turned off, select Change and turn on Camera access for this device.
E. Make sure the correct device is enabled. If you have a built-in camera and an external webcam plugged in, applications can get confused about which one to use. Check the application's settings and find the option to select your preferred device.
F. Change your webcam system settings. There may be a system setting that interferes with the function of the webcam.
