Why is unity crashing?,How is this crashing unity?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class RANDSPAWN : MonoBehaviour
 {
   public GameObject GO;
     public Transform prefab;
     // Start is called before the first frame update
     void Start()
     {
         for (int i = 0; i < 10; i++)
         {
             Instantiate(prefab, new Vector3(i * 2.0F, 0, 0), Quaternion.identity);
         }
         /*
         for (int a = 0; a < 10; a++)
         {
             for (int b = 0; b < 10; b++)
             {
                 for (int c = 0; c < 10; c++)
                 {
                      Instantiate(GO, new Vector3(a,b,c), Quaternion.identity);
                    // clone.transform.position = Vector3.Lerp(clone.transform.position, new Vector3(a, b, c), Time.deltaTime);
                 }
             }
         }
         */
     }
 
     // Update is called once per frame
     void Update()
     {
         
     }
 }
 

Above is a complete copy and paste of my code. I am just trying to test loop and lerp stuff, so an object spawns and goes to its position so I can see a cube being made and seeing if its hollow or not. However whenever I run this code it complete crashes out unity, using System.Collections; using System.Collections.Generic; using UnityEngine;

 public class RANDSPAWN : MonoBehaviour
 {
   public GameObject GO;
     public Transform prefab;
     // Start is called before the first frame update
     void Start()
     {
         for (int i = 0; i < 10; i++)
         {
             Instantiate(prefab, new Vector3(i * 2.0F, 0, 0), Quaternion.identity);
         }
         /*
         for (int a = 0; a < 10; a++)
         {
             for (int b = 0; b < 10; b++)
             {
                 for (int c = 0; c < 10; c++)
                 {
                      Instantiate(GO, new Vector3(a,b,c), Quaternion.identity);
                    // clone.transform.position = Vector3.Lerp(clone.transform.position, new Vector3(a, b, c), Time.deltaTime);
                 }
             }
         }
         */
     }
 
     // Update is called once per frame
     void Update()
     {
         
     }
 }

As you can see instantiate prefab is from the tutorial and that is crashing mine and a friends unity install is there anything I am doing wrong?
