Many of the warning messages that your Windows 11 camera is being used by another application appear for the same reasons. Either something in the background is preventing the camera from working, or something left open triggering the camera.
The warning text is generally similar to each other in the problems that occur when accessing the camera on the computer. The situation of using a different application is experienced in every operating system version. In fact, this event is related to the busyness of the system. Of course, it’s also possible for an app that was last run to keep the camera open.

- Camera errors 0xa00f4243, 0xc00d3704 and 0xa00f4289
- Windows 11 error 0xa00f4288 all cameras are reserved
