Hello! What is the problem?
I get this error: NullReferenceException: Object reference not set to an instance of an object

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

[System.Serializable]
public class inventorySlot
{
    public int slotID;
 
}

public class inventoryDisplay : MonoBehaviour {

    public GameObject slotPrefab;
    public int slotsCount = 36;
    public inventorySlot[] slots;


    GameObject slotsBody;


    private void Awake()
    {
        slots = new inventorySlot[slotsCount];
        
    }

    private void Start()
    {


        slotsBody = GameObject.Find("SlotsBody");

        for(int i = 0; i < slotsCount; i++)
        {
            Instantiate
            slots*.slotID = 1;*

}
}

}

After you instantiate an array of objects (any class type, not just UnityEngine.Objects), you also have to instantiate each object in the array.

The Instantiate() function (which you’re not using [the correct syntax][1] for) is specifically for copying a GameObject from a prefab or an existing GameObject, and placing the copy into the scene. To instantiate an instance of a normal class (like your inventorySlot), you do this:

private void Awake()
{
	slots = new inventorySlot[slotCount];

	for (int i=0; i<slotsCount; i++)
	{
		slots *= new inventorySlot();*

_ slots*.slotID = 1;_
_ }_
_}_
