Question Player prefab destroyed when loading into another scene

Hey so I have 2 scenes, one that has the UI and the other which is the real map where you spawn, when you click a button on the first scene it loads just fine, but when I try to move it logs this error

MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.

Your script should either check if it is null or you should not destroy the object.

I tried using the dontdestroyonload but it doesn't seem to be working. Here is a video and the code

This is called in the NetworkManagerUI which is a child of the canvas

Code (CSharp):

1. startHostButton?.onClick.AddListener(async () =>
2.         {
3.             await Authenticate();
4.             _connectedLobby = await CreateLobby();
5.             NetworkManager.SceneManager.LoadScene("GameScene", LoadSceneMode.Single);
6.             // Test();
7.         });

Here is a script attached to the player prefab that executes on spawn

Code (CSharp):

1.     public override void OnNetworkSpawn()
2.     {
3.         base.OnNetworkSpawn();
4.         DontDestroyOnLoad(gameObject);
5.         if (IsLocalPlayer)
6.         {
7.             Debug.Log("CREATED 1");
8.             Starter.instance._cinemachineVirtualCamera.Follow = camTarget;
9.             // Starter.instance._cinemachineVirtualCamera.LookAt = transform;
10.             Starter.instance._cinemachineVirtualCamera.enabled = true;
11.         }
12.         Debug.Log("CREATED 2");
13.         var cc = GetComponent<CharacterController>().enabled = IsClient;
14.         var tp = GetComponent<ThirdPersonController>().enabled = IsClient;
15.         var rp = GetComponent<BasicRigidBodyPush>().enabled = IsOwner;
16.         var sa = GetComponent<StarterAssetsInputs>().enabled = IsOwner;
17.         var pi = GetComponent<PlayerInput>().enabled = IsOwner;
18.      
19.         transform.position = spawnPoint.position;
20.         transform.rotation = spawnPoint.rotation;
21.     }
