Buttons work in the Editor but not in the build... WHY!

I'm not sure if I should switch back to an older version of Unity3d but the one I am using right now is 2017.3.1f1. So my game works flawlessly in the editor. I hit play and everything is just how I like it, I can press all the buttons and they bring me to the multiplayer, options, etc... But when I BUILD & RUN the game, I can't press the buttons! Alright so maybe I should make another project. Cleanslate. I make a button using this script:

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; public class ChickenButtScript : MonoBehaviour { public GameObject ChickenButt_Text; public void ChickenButton () { ChickenButt_Text.SetActive (true); } }

I build the game and runnnn...

SAME FREAKIN PROBLEM! I have an EventSystem but STILL! It's just an image hanging there and I can't press the button! Does anyone else have the same issue with this version?! This didn't happen before. I'd really appreciate the feedback. Please and Thank you.
