Answer 1

Follow these steps in order on Windows 11 to fix the camera error:

1. Check camera privacy settings
   1. Select Start > Settings > Privacy & security > Camera.
   2. Make sure Camera access is turned On.
   3. Make sure Let apps access your camera is turned On.
   4. In Choose which Microsoft Store apps can access your camera, turn On the apps that should use the camera.
   5. If using desktop apps (browsers, Teams, etc.), scroll to Allow desktop apps to access your camera and turn this On.
2. Close other apps that might be using the camera
   1. Close all apps that could use the camera (Teams, Zoom, browsers, etc.).
   2. Right‑click the taskbar and select Task Manager.
   3. In Processes, look for any app using the camera and select End task.
   4. Reopen the Camera app and test again.
3. Test the camera in the built‑in Camera app
   1. Select Start > Camera.
   2. If prompted, allow camera access.
   3. If the preview works here but not in another app, adjust that app’s own camera settings.
4. Update Windows and camera drivers
   1. Select Start > Settings > Update & Security > Windows Update > Check for updates.
   2. If View optional updates appears, open it and install any camera‑related updates.
   3. Restart the PC after updates.
   4. Then select Start > Device Manager.
   5. Expand Cameras.
   6. Right‑click the camera device > Update driver > Search automatically for drivers.
   7. Restart the PC again and test the Camera app.
5. Run the camera troubleshooter
   1. Use the Get Help app camera troubleshooter: select Run the troubleshooter in Get Help from the camera support article, or open Get Help from Start and search for camera.
   2. Apply any fixes it suggests and restart if requested.
6. Check antivirus or security software
   1. Open the antivirus or security suite installed on the PC.
   2. Look for any webcam/camera protection or privacy shield feature.
   3. Temporarily disable that feature and test the Camera app.
   4. Re‑enable protection after testing.

If the camera still shows only a black screen or no video after these steps, test the camera on another device (for external USB cameras) to rule out hardware failure.
