Polygon Collider 2D Fatal Error

I have problem with polygon collider 2D

 public class provinceManager : MonoBehaviour
 {
     public Transform[] provinces;
     public bool isFirstLaunch;
     public Texture2D map;
     private Color currentColor;
 
     private (int, int) startX = (0, 0);

     private (int, int) startY = (0, 0);
     private (int, int) endY = (0, 0);
 
     void Start()
     {
         isFirstLaunch = true;
     }
     void Update()
     {
         if (isFirstLaunch == true)
         {
             for (int i=0;i<provinces.Length;i++)
             {
                 map = provinces[i].gameObject.GetComponent<provinceController>().worldMap;
                 currentColor = provinces[i].gameObject.GetComponent<provinceController>().color;
                 Color[] c = map.GetPixels(0, 0, map.width, map.height);
                 Texture2D v2worldmap = new Texture2D(map.width, map.height);
                 for (int index = 0; index < c.Length; index++)

                 }
                 v2worldmap.Apply();
                 v2worldmap.filterMode = FilterMode.Point;
                 Rect rec = new Rect(startX.Item1-1f, startY.Item2+2f, endX.Item1-startX.Item1+3f, endY.Item2-startY.Item2-3f);
                 float posX = (startX.Item1 + endX.Item1) / 2f - (map.width / 2f);
                 float posY = (startY.Item2 + endY.Item2) / 2f - (map.height / 2f);
                 Vector2 newPos = new Vector2(posX, posY);
                 provinces[i].transform.Translate(newPos,Space.World);
                 provinces[i].gameObject.GetComponent<SpriteRenderer>().sprite = Sprite.Create(v2worldmap, rec, new Vector2(0.5f, 0.5f), 1f);
                 PolygonCollider2D collider = provinces[i].gameObject.AddComponent<PolygonCollider2D>() as PolygonCollider2D;
             }
             isFirstLaunch = false;
         }
     }
 }

When I start play mode it shows an error alt text
