Custom camera script causes player to fall through the world?

I was working on a custom top down camera script for a game. But for some reason the camera seems to force the player through the earth whenever I zoom in and out with my custom camera.

Heres a gif and also a link to the codeshare if you want to use it in Studio and see if you have the same problem.

Thank you for your time and hopefully we can solve this because I am really confused.
