Unity clone won't appear

I'm new to coding and i'm trying to spawn a clone of a ball in unity, but it won't appear. It does spawn at the spawn point but it doesn't appear.

Here is my code:

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

public class GameController : MonoBehaviour
{

    public GameObject ball;
    public Transform spawnPoint;

    // Start is called before the first frame update
    void Start()
    {
        SpawnBall();
    }

    // Update is called once per frame
    void Update()
    {
        
    }

    void SpawnBall()
    {
        Instantiate(ball, spawnPoint.position, Quaternion.identity);
    }

}

Edit: it's a 3d game and the mesh renderer is enabled.
