2D - FollowCam causes player sprite to disappear

I'm using a simple script attached to the camera that causes it to track the player's movements exactly, keeping the player sprite in the center of the screen. Here's all the code that makes it work:

 public GameObject player;
 
 void Update()
 {
     if (player == null) return;
     Vector2 destination = player.transform.position;
     transform.position = destination;
 }

It works, but it causes the player sprite to disappear from view when the sprite object is attached to the script. When I remove the object, the sprite appears as normal. What could be causing this?
