    public GameObject[] weapons;
    public int selected;
    public int slots;

 void Update()
    {
 for (int i = 0; i < weapons.Length; i++)  //The "iBall" for-loop Goes through all of the Array.
        {
            if (i == selected) //If "iBall" for-loop calls the current object, skip it.
            {
                weapons[selected].gameObject.SetActive(true);
            }
            else //If "iBall" for-loop is anything but the current gameobject, deactivate it.
            {
                weapons[selected].gameObject.SetActive(false);
            }
        }
}

I think you have to change:

weapons[selected].gameObject.SetActive(true);

To

weapons*.gameObject.SetActive(true);*

I’m curious why you put weaponsManager into the array, but if it’s for some excercise or testing purposes then play with the code I wrote. I introduced activateAll bool, which if false deactivates all the gameobjects in the array except the one the script is on, and to the contrary, if true activates all the gameobjects in the array, still not touching weaponsManager. I used Linq extension methods. Enjoy:

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

public class weaponsManager : MonoBehaviour
{
	public GameObject[] weapons;
	public bool activateAll;
	
	void Update() => weapons.Except(new GameObject[]{gameObject}).ToList().ForEach(g=>g.SetActive(activateAll));
}
