Application.LoadLevel(Application.LoadedLevel) causes freeze

Hi there, have some issue with the Application.loadedLevel() methodcall.

My application activates a canvas if the player health <= 0 and set Time.timeScale to 0.

If I click the retry button it loads the actual loaded level again. Unfortunately everything is freezed after the level has been loaded. Thank u guys in advance!

Provide some Code:`

 void Start () {
         deathUI.SetActive(false);
     }
 
     // Update is called once per frame
     void Update() {
         if (attComp.getHealth() <= 0)
         {
             deathUI.SetActive(true);
             Time.timeScale = 0;
         }
     }
     public void retry()
     {
         Time.timeScale = 1;
         Application.LoadLevel(Application.loadedLevel);
         
     }
