how to stop the score from adding upon death?

I have a player that get points for avoiding obstacle but when my player dies, the points still adds up. so how do I stop my player from getting points upon death? I tried using time.timescale = 0; it works half way but when i click restart, the game is still paused. so I decided that i should stop the score from adding when player died which i can't figure out how to do so xD. sorry.... i'm new and it's been a while since i started making this first game of mine

this is my Destroy player script:

 public GameObject gameOverText;
 public GameObject restartButton;
 public ScoreManager manager;
 // Use this for initialization
 void Start () 
 {

 }
 
 // Update is called once per frame
 void Update () 
 {
 }
 void OnTriggerEnter2D(Collider2D other)
 {
          
     if (other.gameObject.CompareTag ("Player")) {
         Destroy (other.gameObject);
         Restart ();

     }
 }
 void Restart()
 {
     gameOverText.SetActive (true);
     restartButton.SetActive (true);
 }

}

and this is the scoremanager

 public Text scoreText;
 private int Points;

 // Use this for initialization

 public void Start () 
 {
     Points = 0;
     scoreText.text = "score:" + Points;
 }
 
 // Update is called once per frame
 public void AddPoints(int amount) 
 {
     Points = Points + amount;
     scoreText.text = "score:" + Points;
 }

}
