Random spawning on 4 cubes.

Hello guys.

public class SpawnMeteoritov : MonoBehaviour {

    public GameObject ObjectToSpawn;
    public float RateOfSpawn = 1f;

    private float nextSpawn = 0f;

    void Update()
    {

        if (Time.time > nextSpawn)
        {
            nextSpawn = Time.time + RateOfSpawn;

           
            Vector2 rndPosWithin;
            rndPosWithin = new Vector2(Random.Range(-1f, 1f), Random.Range(-1f, 1f));
            rndPosWithin = transform.TransformPoint(rndPosWithin * .5f);
            Instantiate(ObjectToSpawn, rndPosWithin, transform.rotation);
        }
    }
  
}

My script making this. I have 1 game objects(CUBE) when i put my script in to this gameobject(CUBE), he will randomly spawn next game objects in this (CUBE) every 5seconds(example).
And my script makes it that when I start the script, it spawns in every (CUBE-we have 4 CUBES) every 5 seconds another object. This means that (4 CUBES) spawns 4 game objects. And I need to spawn only 1(i must make from this 4 CUBES only 1 GameObject, where next game objects will be randomly spawn).

You can see that every 5 seconds on these 2 cubes, they spawn 2 game objects. I need on these 2 cubes, spawning 1 game object.
Thank you for every answer.

If I am understanding your issue correctly, I believe you want one game object (a cube) to spawn additional game objects periodically. But every time you spawn a new game object, they are themselves spawning new game objects, etc. So here would be a couple of solutions to try:
Make your ObjectToSpawn game object a different object than the original, with a different (or no) script attached to it.
After Instantiating your ObjectToSpawn, disable the SpawnMeteoritov component on it so it does not spawn its own objects.
