I wanted to roll 2 dices at a single time and needs to get the result. But my first dice is working properly not the second. Sharing my script here.

public class Dice : MonoBehaviour { Rigidbody rb;

 bool hasLanded;
 bool thrown;

 Vector3 initPosition;

 public DiceSide[] diceSides;
 public int diceValue;

 // Start is called before the first frame update
 void Start()
 {
     initPosition = transform.position;
     rb = GetComponent<Rigidbody>();
     rb.useGravity = false;
     
 }
 
 public void RollDice()
 {
     Reset();
     if(!thrown && !hasLanded)
     {
         thrown = true;
         rb.useGravity = true;
         rb.AddTorque(Random.Range(0, 700), Random.Range(0, 700), Random.Range(0, 700));
     }
     else if(thrown && hasLanded)
     {
         //reset the dice position
         Reset();
     }
 }

 void Reset()
 {
     transform.position = initPosition;
     rb.isKinematic = false;
     thrown = false;
     hasLanded = false;
     rb.useGravity = false;
 }

 void Update()
 {
     if(rb.IsSleeping() && !hasLanded && thrown)
     {
         hasLanded = true;
         rb.useGravity = false;
         rb.isKinematic = true;

         //side value check
         SideValueCheck();

     }
     else if(rb.IsSleeping() && hasLanded && diceValue ==0)//If dice didnt drawn properly it will re-roll
     {
         //roll the dice again
         RollAgain();
     }
 }

 void RollAgain()
 {
     Reset();
     thrown = true;
     rb.useGravity = true;
     rb.AddTorque(Random.Range(0, 700), Random.Range(0, 700), Random.Range(0, 700));
 }

 void SideValueCheck()
 {
     diceValue = 0;
     foreach(DiceSide side in diceSides)
     {
         if(side.OnGround())
         {
             diceValue = side.sideValue + side.sideValue1;
             //send results to GameManager script
             GameManager.instance.RollDice(diceValue);
         }
     }
 }

}
