smoothly move an object from one vector to another (crashing unity)

I'm trying to move an object from one point to another (it's important that the numbers increment exactly), I want the object to move there smoothly, though. here's the code I used, Unity crashed when I tried it:

     public float XPos = 2;
     public Vector2 playerPos = new Vector2 (2, 2);
 
     void Update ()
     {
         playerPos = new Vector2 (XPos, 2);
         //Mathf.Round (XPos);
         transform.position = playerPos;
         if(Input.GetKeyDown (KeyCode.A))
         {
             Move();
         }
     }
     void Move ()
     {
         float i = XPos + 1;
         while (XPos < i )
         {
             transform.Translate(Vector3.up * Time.deltaTime);
         }
     }
