Camera not detected -ZED SDK 4.0

whenever i connect my ZED2 camera it opens in the ZED explorer but when i try to run the camera control sample it says “Camera not detected” I tried changing the port but still didn’t work

that is probably because the camera is already in use in ZED Explorer ?

did you ever find a fix to this?
