What if the camera is occupied?

When we turn on the camera, we sometimes encounter the prompt "camera is occupied" and cannot preview the local image. What do we do?

The reason for analysis should be that the third-party program occupies the camera, or is optimized by other optimization software, causing the camera to be unusable.
