any help?

The trick is to not deactivate the GameObject, but the Component.

this.GetComponent<SpriteRenderer>().enabled = true;

is Prefered over

this.gameObject.SetActive(true);

try something like this

var pf0 = Instantiate (prefab, transform.position, transform.rotation);
pf0.SetActive(false);

If theres multiple prefabs I would consider a “for” hope this helped
