how to fix app

Follow these steps to fix the “another app is using the camera” issue in Windows 10:

1. Close background apps that might be using the camera
   1. Right-click the taskbar and select Task Manager.
   2. In Processes, look for apps that could use the camera (for example: browsers, video/meeting apps, camera utilities).
   3. Right-click each suspected app and select End task.
2. Check camera privacy settings
   1. Select Start > Settings > Privacy & security > Camera.
   2. Under Camera access, make sure it is turned On. If it is off and greyed out, an administrator must turn it on.
   3. Make sure Allow apps to access your camera (or Let apps access your camera) is turned On.
   4. Scroll down and turn on camera access for the specific apps that need it under Choose which Microsoft Store apps can access your camera.
   5. If using non–Store apps (browsers, video conferencing, etc.), make sure Allow desktop apps to access your camera is turned On.
3. Test the camera in the Camera app
   1. Open Start > Camera.
   2. Check if the preview works.
   3. If the camera works here but not in another app, adjust that app’s own camera settings.
4. Restart and update Windows
   1. Select Start > Settings > Update & Security > Windows Update > Check for updates and install any available updates (including optional camera-related updates).
   2. Restart the PC via Start > Power > Restart (do not just wake from sleep).
   3. Test the camera again with the Camera app and then with the target app.
5. Run the camera troubleshooter
   • Use the automated troubleshooter via Run the troubleshooter in Get Help: Run the troubleshooter in Get Help.

If the message persists only in a specific app after these steps, the problem is likely with that app’s configuration or compatibility rather than Windows itself.
