Linerenderer not following game object

So I have done the first video of the angry birds tutorial and I have a problem with the line renderer. The meteor (I am using a ball instead) is supposed to have a band (line renderer) attached to it, but it's not following the ball. I have searched for solutions, but it seems like no one else is having the same problem, maybe because line renderer has been updated (IDK), and I have been searching for errors in the code, but I can't find any mistakes. Help would be appreciated. Here is a picture: Here is the code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class ProjectileDragging : MonoBehaviour

     public float maxStretch = 3.0f;

     public LineRenderer catapultLineBack;
 
     private Rigidbody2D Ball;
     private SpringJoint2D spring;
     private Transform catapult;
     private Ray rayToMouse;
     private Ray leftCatapultToProjectile;
     private float maxStretchSqr;
     private float circleRadius;
     private bool clickedOn;
     private Vector2 prevVelocity;
 
     private void Awake()
     {
         spring = GetComponent<SpringJoint2D>();
         catapult = spring.connectedBody.transform;
 
         Ball = GetComponent<Rigidbody2D>();
     }
 
     void Start()
     {
         maxStretchSqr = maxStretch * maxStretch;
 
         LineRendererSetup();
         //catapult = GetComponent<Transform>();
         leftCatapultToProjectile = new Ray(catapultLineFront.transform.position, Vector3.zero);
