Why is the new spawned object removed?

Question

Unity

I have an array of objects, I'm spawning them via InvokeRepeating, and I need to delete the object when it touches the collider.
I create a clone of an object prefab, then this clone, when it touches the collider, it is not deleted, but the clone that just spawned in another place is deleted, I can’t find a solution anywhere, please

help ItemSpawn.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ItemSpawn : MonoBehaviour
{
   
    public GameObject[] clothes; //объекты, кторые надо спавнить
    public Transform objspawn;// координата для спавна
    public float spawnrate;//частота спавна
    public float speed;// скорость движения объекта
    public int rand;//рандом для clothes

    
    public GameObject duplObj; //клон clothes
    public int i;
    void Start()
    {

        //спавн объектов через заданное время spawnrate
         InvokeRepeating("SpawnObj", 1f, spawnrate);
    }

   
    void Update()
    {
        i = rand;
        
    }

    void SpawnObj()
    {
     //сам спавн   
        rand = Random.Range(0, clothes.Length);
       
        //тут создается клон объекта
               duplObj= Instantiate(clothes[i], objspawn.position, transform.rotation);
      
    }
}

ItemMovement.cs which is attached to the object

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ItemMovement : MonoBehaviour
{
    ItemSpawn itemSpawn;
     
    void Start()
    {
        itemSpawn = GameObject.Find("Main Camera").GetComponent<ItemSpawn>();//для определения нахождения скрипта на объекте
        
    }

    private void FixedUpdate()
    {
        transform.Translate(itemSpawn.speed * Time.deltaTime, 0, 0);//движение объекта
    }
  

    //Здесь происходит уничтожение клона, если он соприкасается с объектом, у которого тег Destroy
    private void OnTriggerEnter2D(Collider2D collis)
    {
        if (collis.gameObject.tag == "Destroy")
        {
            Destroy(itemSpawn.duplObj);

        }

    }
}

Answer 1

Here's what I found out, and this: if you delete the clone before the specified amount of spawnrate has passed, then the new clone is deleted.
But how to fix it
, I even tried through the coroutine, but everything is the same

You seem to be constantly updating the duplObj variable during spawn. As a result, it always points to the newly created object, which you delete in ItemMovement.OnTriggerEnter2D
