Hi,
When you open the camera, what exactly do you see, such as a plain black screen, a gray screen with a lock icon, or an error code?
Is this a laptop, and are you referring to the built-in camera?
What is the make and model of your device? In the search bar, type MSINFO32 and press Enter, then please share a screenshot of that window.
In the meantime, please try the following:
Method 1: Some laptops have a physical key to enable or disable the camera. Look for a key with a camera icon (usually on the F1–F12 keys). Press that key, or press Fn + the camera key, to enable the camera.
Method 2: Check the camera lens carefully to see if there is a physical cover or shutter. If so, slide it open to uncover the webcam.
Method 3:
- Press Windows key + X and select Device Manager
- Expand Cameras or Imaging devices
- Right-click your camera and select Uninstall device
- Make sure to check “Delete the driver software for this device” if prompted
- Restart your PC
After restarting, check if the issue is resolved.
