Issue with scene changing in Android Build. Buttons register touches but the functions called dont work.

I am trying to figure this out. I built an .apk to load onto my device to test it out. I am not using unity remote, as it does not work for me. Nor' am I using any debug services like ADB as my usb port on my phone is not working.
I run the application fine on the phone. I have a Samsung S9+ with the highest API being 29 I believe currently. I wanted to assume that the OnClick() callback function doesn't work with Touch Phones, but I couldn't find a google search that supported that argument.
I have a start button that changes the scene to the main level selector. I use Application.LoadScene(int sceneIndex) to change scenes. This is where I assumed the OnClick() callback doesn't work because the animation for the button script works perfectly; it does its thing.
Is there something I am missing?
Here is the code. Everything runs completely fine on unity editor and PC.

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 using System;
 using SimpleJSON;
 
 public class HomeController : BaseController
 {
     private const int PLAY = 0, RATE = 2;
     public ToggleButton tgSound, tgMusic;
     protected override void Start()
     {
         base.Start();
         GameState.currentMode = GameState.GameMode.Challenge;
         tgSound.IsOn = Sound.instance.IsEnabled();
         tgMusic.IsOn = Music.instance.IsEnabled();
         Music.instance.Play(Music.Type.MainMusic, true);
     }
 
     public void OnToggleSound()
     {
         tgSound.Toggle();
         Sound.instance.SetEnabled(tgSound.IsOn);
         Sound.instance.PlayButton();
     }
 
     public void OnToggleMusic()
     {
         tgMusic.Toggle();
         Music.instance.SetEnabled(tgMusic.IsOn, true);
         Sound.instance.PlayButton();
     }
 
     public void OnClick(int index)
     {
          Debug.Log("Button Pressed");
         Sound.instance.PlayButton();
         Debug.Log("Sound Played");
         switch (index)
         {
             case PLAY:
                 
                 CUtils.LoadLevel(1);
                 Debug.Log("Level Loaded");
                 
                 GameState.currentMode = GameState.GameMode.Challenge;
                 break;
             case RATE:
                 CUtils.RateGame();
                 break;
         }
     }
 }


This code handles the actual scene change.

     public static void LoadLevel(int levelIndex)
     {
         SceneManager.LoadScene(levelIndex);
         SetPreviousScene();
     }
