Unity keep crashing when loading scene from a couritne (Unity 5.x)

Question

I am trying to send a POST request to an API and load a scene when the![alt text][1]script gets a response, but it's crashing the Unity.

Version 5.x

Thanks in advance.

 using UnityEngine.SceneManagement;
 
 public class LogInGamer : MonoBehaviour
 {
     [SerializeField] private CredentialsConfig credentialsConfig;
     [SerializeField] private  string PORT;
     [SerializeField] private  string ServerLink;
     [SerializeField] private string sucsessfulLoginScene;
 
     [SerializeField] private InputField gamerIdInputField;    
     [SerializeField] private InputField gamerPasswordInputField;
     private  string gamerId = "";
     private string password = "";
     private IEnumerator coroutine;
     private bool _isLoggedIn;
     [SerializeField] private GameObject registrationPanel;
 
     private void Start() {
         PORT = credentialsConfig.PORT;
         ServerLink = credentialsConfig.URL;
     }
 
     public void ActivateRegistationPanel()
     {
         registrationPanel.SetActive(true);
     }
 
     public void TakeIdInput()
     {
         gamerId = gamerIdInputField.text;
     }
 
     public void TakePasswordInput()
     {
         password = gamerPasswordInputField.text;
     }
 
     public void HitLogInApi()
     {
         coroutine = LogIn();
         StartCoroutine(coroutine);
     }

         WWWForm form = new WWWForm();
         form.AddField("gamerid", gamerId);
         form.AddField("password", password);
         form.AddField("projectId", credentialsConfig.projectId);
 
         using (UnityWebRequest www = UnityWebRequest.Post(ServerLink + ":" + PORT + "/unity/login", form))
         {
             www.SetRequestHeader("Accept", "application/json");
 #if !UNITY_5
             yield return www.SendWebRequest();
 
             if (www.isNetworkError || www.isHttpError)

             }
             else
             {
                 Debug.Log("Form upload complete!");
                 if(www.responseCode == 200)
                 {
                     this.gameObject.SetActive(false);
                 }
                 var c = www.downloadHandler.text;
                 Debug.Log("Response-> " + c);
             }
 #else
             yield return www.Send();
 
             if (www.isError)
             {
                 Debug.Log(www.error);
             }

                 {
                     //SceneManager.LoadSceneAsync(sucsessfulLoginScene, LoadSceneMode.Single);
                     SceneManager.LoadScene(sucsessfulLoginScene, LoadSceneMode.Single);
                 }
                 var c = www.downloadHandler.text;

You're not instantiating sucsessfulLoginScene anywhere.

In Unity, go to File > Build Settings, and set your sucsessfulLoginScene to one of the values in "Scenes In Build". For example, sucsessfulLoginScene = "Scenes/LoginScene".
