Your cameraView variable isn’t matching with the first C. That might be the reason why FirstPerson isn’t working, because it’s not triggering.
Since you’re setting both of these camera views at runtime once, I’m assuming that ThirdPerson simply just overrides and is the camera view you’re seeing. That could be the root of the unexpected behavior.
By any chance, are you using any other camera modules that might interfere with CameraService?
