Reloading a Scene when I die doesn't work for the second level.

For some reason this works for the first level but not the second.

I am only using 3 lines of code to respawn the player.

 public void Respawn()
 {
       Time.timeScale = 1.0f;
       SceneManager.LoadSceneAsync(SceneManager.GetActiveScene().buildIndex);
       player.transform.position = 
       GameObject.FindGameObjectWithTag("SpawnPoint").transform.position;
 }
