Troubleshooting guide
How to fix the problem
In Windows 11 Settings > Privacy & Security > Camera view app permissions and recent activity if displayed; In Windows 10, go to Privacy > Camera. Desktop applications may not be fully listed, so the list alone is not sufficient to determine all activities. After closing the video calling apps, check the camera indicator and the physical cover.
If the problem persists
Check permissions for individual apps and desktop apps. Activity history may not show all apps; close the suspicious app and watch the camera indicator.
