Bug GameObject not rendering

I've been working on a small game project to learn how to use Unity and how to use C# for game dev. I am trying to get my enemy sprites to instantiate, and they are, but they don't show in the game view for some reason. I checked the camera Z position and its correct, I've made sure that the sprite render is set to be on, I am instantiating the sprites inside of the camera view. All of the trouble shooting things that I have been told I have tried and it is still not working.
The code:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class EnemyLogic : MonoBehaviour
7. {
8.     public GameObject enemyPrefab;
9.     public float respawnTime;
10.     public UILogic logic;
11.     private GameObject lastActualEnemyCreated;
12.  
13.     float screenWidth;
14.     float screenHeight;
15.     private float timer = 0;
16.     // Start is called before the first frame update
17.     void Start()
18.     {
19.         respawnTime = Random.Range(1f, 5f);
20.         screenHeight = Screen.height;
21.         screenWidth = Screen.width;
22.         logic = GameObject.FindGameObjectWithTag("Logic").GetComponent<UILogic>();
23.         spawn();
24.     }
25.  
26.     // Update is called once per frame
27.     void FixedUpdate()
28.     {
29.         if (logic.checkIfAlive() && !logic.Paused)
30.         {
31.             if (timer < respawnTime)
32.             {
33.                 timer += Time.deltaTime;
34.             }
35.             else
36.             {
37.                 spawn();
38.                 timer = 0;
39.             }
40.         }
41.     }
42.  
43.     private void spawn()
44.     {
45.         int side = Random.Range(0, 4);
46.         float spawnX = 0f;
47.         float spawnY = 0f;
48.  
49.         switch (side)
50.         {
51.             case 0: //Top side
52.                 spawnX = Random.Range(0f, screenWidth-1f);
53.                 spawnY = screenHeight;
54.                 break;
55.             case 1: //right side
56.                 spawnX = screenWidth;
57.                 spawnY = Random.Range(0f, screenHeight-1f);
58.                 break;
59.             case 2: //Bottom side
60.                 spawnX = Random.Range(0f, screenWidth-1f);
61.                 spawnY = 0f;
62.                 break;
63.             case 3: //Left side
64.                 spawnX = 0f;
65.                 spawnY = Random.Range(0f, screenHeight-1f);
66.                 break;
67.         }
68.         Vector3 spawnPosition = Camera.main.ScreenToWorldPoint(new Vector3(spawnX, spawnY, 0f));
69.         lastActualEnemyCreated = Instantiate(enemyPrefab, spawnPosition, transform.rotation);
70.         lastActualEnemyCreated.SetActive(true);
71.     }
72.  
73.    
74. }
