### Current Behavior

Hi all,

Currently using Community Toolkit Camera to develop a camera app. When I Stop Preview camera, it work properly. The issue was when I tried to use the StartCameraPreviewCommand, it didn't restart the camera preview at all. There are no exception occur or any errors captured.

Please refer to the screen recorder below and attached Debug log from VS2022.
