My webcam on my lenovo has stopped working. It isn't broken, but none of my apps can find it. All my drivers are up to date, my privacy settings allow it to work, and i have no antivirus programme stopping it. Help?

Webcam
is not detected or unable to turn on the camera. Before going to the
below troubleshooting flow, please give a quick check. Try different
apps to identify whether it is a hardware problem. Different apps
include Youcam, Skype, Line, Facebook messenger, etc.

The issue may be caused by:

• Camera driver is out of date or not installed correctly
• Camera was disabled in Device Manager
• Camera was set off under Privacy or Lenovo Settings
• Hardware is broken

Confirm webcam is on under Privacy

1. In Windows 8/8.1, open Charms Bar via the desktop and click on Settings option. Click on PC info or Change PC settings -> Privacy -> Webcam. Slide on the webcam or configure to Let these apps use my webcam.
2. In Windows 10, open Settings -> Privacy -> Webcam. Slide on the webcam or configure to Let these apps use my webcam.
