Resolved Movement swapped for players

Fix: I had to deactivate the other players camera, now it works.
Updated code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Photon.Pun;
5.  
6. public class PlayerMovement : MonoBehaviour
7. {
8.     [SerializeField] [Range(0, 30)] private float walkSpeed;
9.     [SerializeField] [Range(0, 30)] private float sprintSpeed;
10.     private float speed;
11.     [SerializeField] private CharacterController controller;
12.     public bool isBreaking;
13.     PhotonView view;
14.  
15.     private void Start()
16.     {
17.         view = GetComponent<PhotonView>();
18.  
19.         if (!view.IsMine)
20.         {
21.             Debug.Log("View is not yours, deactivating camera");
22.  
23.             transform.Find("Main Camera").gameObject.SetActive(false);
24.         }
25.     }
26.  
27.     private void Update()
28.     {
29.         if (Input.GetKey(KeyCode.LeftShift))
30.         {
31.             speed = sprintSpeed;
32.         }
33.  
34.         else
35.         {  
36.             speed = walkSpeed;
37.         }
38.  
39.         float x = Input.GetAxis("Horizontal");
40.         float z = Input.GetAxis("Vertical");
41.  
42.         Vector3 move = transform.right * x + transform.forward * z;
43.  
44.         if (!isBreaking && view.IsMine)
45.         {
46.             controller.Move(move * speed * Time.deltaTime);
47.         }
48.     }
49. }
50.  

I'm using Photon to make a multiplayer game. Everything works until another player joins, then the first player is moving the second player and vice versa.
