Billboard nametag not working

So i'm using PUN2 and tryna do nametag billboard for my players but its not working for some reason. I think it has something to do with me destroying the camera on the player controller script. When I load the game the camera is destroyed for the players which has something to do with the phonoview. Im a noob and need some help. Thanks! This is the billboard scriot

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5.  
6.     public class BillBoard : MonoBehaviour
7.     {
8.  
9.  
10.     private Transform mainCameraTransform;
11.  
12.       private void Start()
13.       {
14.           mainCameraTransform = mainCameraTransform.transform;
15.       }
16.  
17.       private void LateUpdate()
18.       {
19.      
20.         {
21.               transform.LookAt(transform.position + mainCameraTransform.rotation * Vector3.forward,
22.   mainCameraTransform.rotation * Vector3.up);
23.           }
24.  
25.       }
26.  
27. }

This is the player controller script:

Code (CSharp):

1.  
2.  
3. using Photon.Pun;
4. using System.Collections;
5. using System.Collections.Generic;
6. using UnityEngine;
7.  
8. public class PlayerController : MonoBehaviour
9. {
10.     [SerializeField] GameObject cameraHolder;
11.  
12.     [SerializeField] float mouseSensitivity, sprintSpeed, walkSpeed, jumpForce, smoothTime;
13.  
14.     float verticalLookRotation;
15.     bool grounded;
16.     Vector3 smoothMoveVelocity;
17.     Vector3 moveAmount;
18.  
19.     Rigidbody rb;
20.  
21.     PhotonView PV;
22.  
23.     void Awake()
24.     {
25.         rb = GetComponent<Rigidbody>();
26.         PV = GetComponent<PhotonView>();
27.     }
28.  
29.     void Start()
30.     {
31.         if (!PV.IsMine)
32.         {
33.             Destroy(GetComponentInChildren<Camera>().gameObject);
34.             Destroy(rb);
35.         }
36.     }
37.  
38.     void Update()
39.     {
40.         if (!PV.IsMine)
41.             return;
42.  
43.         Look();
44.         Move();
45.         Jump();
46.     }
47.  
48.     void Look()
49.     {
50.         transform.Rotate(Vector3.up * Input.GetAxisRaw("Mouse X") * mouseSensitivity);
51.  
52.         verticalLookRotation += Input.GetAxisRaw("Mouse Y") * mouseSensitivity;
53.         verticalLookRotation = Mathf.Clamp(verticalLookRotation, -90f, 90f);
54.  
55.         cameraHolder.transform.localEulerAngles = Vector3.left * verticalLookRotation;
56.     }
57.  
58.     void Move()
59.     {
60.         Vector3 moveDir = new Vector3(Input.GetAxisRaw("Horizontal"), 0, Input.GetAxisRaw("Vertical")).normalized;
61.  
62.         moveAmount = Vector3.SmoothDamp(moveAmount, moveDir * (Input.GetKey(KeyCode.LeftShift) ? sprintSpeed : walkSpeed), ref smoothMoveVelocity, smoothTime);
63.     }
64.  
65.     void Jump()
66.     {
67.         if (Input.GetKeyDown(KeyCode.Space) && grounded)
68.         {
69.             rb.AddForce(transform.up * jumpForce);
70.         }
71.     }
72.  
73.     public void SetGroundState(bool _grounded)
74.     {
75.         grounded = _grounded;
76.     }
77.  
78.     void FixedUpdate()
79.     {
80.         if (!PV.IsMine)
81.             return;
82.  
83.         rb.MovePosition(rb.position + transform.TransformDirection(moveAmount) * Time.fixedDeltaTime);
84.     }
85. }
86.
