Fruit ninja course

I'm following a course in the udemy website. Earlier my project could not destroy the fruit by making them disappear. Now I succeeded and found that the codes given by the tutorial were not properly written as other students had the same problem. However, now that i added sliced fruits, both the spawned fruits and the sliced fruits just don't appear anymore. I have inserted the link for the project so anyone can download to test it out https://drive.google.com/file/d/1akEMR8eqHrJA0_0Me_B1xwXfvJMkuup-/view?usp=sharing - password not required . The picture has also been inserted so you can see the fruits just refuse to appear.

edit (moved from answer)
I already carefully tested the project. Whether the fruits and fruit cuts are enabled / disabled, the results are the same. I am pasting the spawning codes here. Let me know if you need more codes.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class FruitSpawner : MonoBehaviour
 {
     public GameObject fruit;
     public float maxX;
 
     // Start is called before the first frame update
     void Start()
     {
         Invoke("StartSpawning", 1f);
     }
 
 
     public void StartSpawning()
     {
         InvokeRepeating("SpawnFruitGroups", 1, 6f);
     }
 
     public void StopSpawning()
     {
         CancelInvoke("SpawnFruitGroup");
         StopCoroutine("SpawnFruit");
     }
 
 
     public void SpawnFruitGroups()
     {
         StartCoroutine("SpawnFruit");
     }
 
 
     IEnumerator SpawnFruit()
     {
         for (int i = 0; i < 5; i++)
         {
             float Rand = Random.RandomRange(-maxX, maxX);
             Vector3 pos = new Vector3(Rand, transform.position.y, 0);
             GameObject f = Instantiate(fruit, pos, Quaternion.identity) as GameObject;
             f.GetComponent<Rigidbody2D>().AddForce(new Vector2(0, 15f), ForceMode2D.Impulse);
             f.GetComponent<Rigidbody2D>().AddTorque(Random.Range(-20f, 20f));
             yield return new WaitForSeconds(0.5f);
         }
     }
 }
