If I add a character controller to my player, I fly up forever.

Basically I have a player object(capsule). However, when I attach a character controller to it, it just goes flying up indefinitely. I have no clue why or how this is happening. Any help is appreciated.

Here are all the scripts on the player and the player prefab itself: Data package from July 22nd. - FileTransfer.io.

The player also has mirror components implemented on it as this project has mirror on it.
Thank you.

Character controller makes collision possible. If you collide with something, you need gravity to keep you on the ground. You could try adding a rigidbody
