My UI Buttons stopped working

My UI buttons worked until today, after I imported some Assets and played around with them all my UI Buttons on that scene stopped working. So I deleted all the imported Assets but the Buttons are still not working. When I switch scenes and play game it works perfectly. In my event system I've checked force Module Active in my Canvas > Gameobjects Interacble and Raycast Target is checked. I've double check the Event Trigger Script component and the coding, but nothing is working. I doubt there's anything wrong with the coding.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.EventSystems;
 
 public class Movement : MonoBehaviour {
 
     public bool mouseOff = false;
 
     public void MoveLeftButton(string moveleft)
     {
         Player.horizVel = -3;
 
     }
 
     public void MoveRightButton(string moveright)
     {
         Player.horizVel = 3;
 
     }
 
     public void MoveLeftButtonStop(string moveleftstop)
     {
         StopXVel();
 
     }
 
     public void MoveRightButtonStop(string moverightstop)
     {
         StopXVel();
 
     }
 
 
     public void OnPointerEnter(PointerEventData eventData)
     {
         MouseOffTrue();
 
     }
 
     public void OnPointerExit(PointerEventData eventData)
     {
         MouseOffFalse();
 
     }
 
     public void OnPointerDown(PointerEventData eventData)
     {
         MouseOffTrue();
 
     }
 
 
 
     void MouseOffTrue()
     {
         mouseOff = true;
     }
     void MouseOffFalse()
     {
         mouseOff = false;
     }
     void StopXVel()
     {
         Player.horizVel = 0;
     }
 }
