camera script not working

Hi there, I’m making a 2d game, is almost finished but the camera scripts is missing, I’d like to make a camera like super mario, I created a function to follow the player it work, but when the transformation changes the camera stops following him. helpe me please =) !

  public class Cam : MonoBehaviour
  {
      public Transform player;
  
      // public Transform [] target; //you can make an array of transform???
  
      /// 1 transformation
      /// 2 transformation
      /// 3 transformation
  
      public float distanceToPlayer;
      public float speedCam;
      public float height;
  
  
  
      private void Start()
      {
          player = GameObject.FindGameObjectWithTag("Player").transform;
      }
  
      void Follow()
      {
          Vector3 newPosition = player.position + new Vector3(0, height, -distanceToPlayer);
          transform.position = Vector3.Lerp(transform.position, newPosition, speedCam * Time.deltaTime);
  
          //
      }
  
      private void Update()
      {
          Follow();
      }
  }
