Unity creates empty cloned object

I'm building a 2D game. I have a GameObject in my scene called "Player" with the tag "Player". In the script that handles my input and my camera movement, I have a call to find the player using "FindGameObjectWithTag", and the player is already in the scene, not instantiated through code.

When I hit play, the camera does not follow the player. Instead, it follows an invisible object. When hitting the jump key, I get the following error: "MissingComponentException: There is no 'Rigidbody2D' attached to the "Player(Clone)" game object, but a script is trying to access it."

Player(Clone) does not appear in the hierarchy like normal clone instantiations do. What is unity doing?
