Making a button in 3d space face a player without disabling the button functionality

Code (CSharp):

1. public Transform target;
2.  
3.     void Update()
4.     {
5.         // Rotate the camera every frame so it keeps looking at the target
6.         transform.LookAt(target);
7.  
8.         // Same as above, but setting the worldUp parameter to Vector3.left in this example turns the camera on its side
9.         //transform.LookAt(target, Vector3.left);
10.     }

this is my code for making a button in 3d face my character but it disables the button and it becomes unclickable

 

What do you mean by a button in 3d space? Are we talking about UnityEngine.UI.Button, or something else?

 

I have it on a canvas in 3d. i want it to look at a player at all times but they get disabled when i add this code
