Unity Freezes after restarting level a few times

Copy your restart script here. Unity mostly freezes when it encounters an infinite loop, so I guess if it only happens at the 4th time, you either have an infinite loop which activates at the 4th try, or you parallely load the maps and after the 3rd load, unity can't handle the 4th one. But that's just blind guessing here.

i tried commenting out the lines as you see still same problem.

  public Canvas deathScreen;
 
     // Use this for initialization
     void Start () 
     {
         //Event$$anonymous$$anager.PlayerDeath += new Event$$anonymous$$anager.GameEvent(PlayerDeath);
         //deathScreen.gameObject.SetActive(false);
     }
 
     void PlayerDeath()
     {
         if (deathScreen != null)
         {
             //deathScreen.gameObject.SetActive(true);
         }
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 
     public void PlayAgain()
     {
         Application.LoadLevel(Application.loadedLevel);
     }
