Could anyone help me with sending the camera back to main?[SOLVED]

There is a teleport script that I’m working with that once it’s used it jumps to the next scene perfectly but, when it does that it ruins my camera rig and I can never go back and the Camera Triggers stop working too.
Getting rid of the last line in ‘Teleport.py’ does the jump to next area I want but, the last line is what is responsible for trying to get back into ‘CineCam’ as the the main camera again.
