If statement not working

I was making a game mod, and needed a random number. It worked fine, but after some time, it broke. I did some debugging, and found that the error lied in the if statement that I used at line 38. How do I fix this?

You do not need to worry about commands starting with KM. That is not relevant to this problem.

 using System.Linq;
 using KModkit;
 
 public class colorNumberCode : MonoBehaviour

     public KMBombInfo bomb;
     public KMAudio audio;
     
     public KMSelectable button1;
     public KMSelectable button2;
     public KMSelectable button3;
     public KMSelectable button4;
     
     public Material[] colorOptions;
     public Renderer led;
     private int ledIndex = 0;
     
     static int moduleIdCounter = 1;
     int moduleId;
     private bool colorPicked = false;
     private bool moduleSolved; 
     
     void Awake()
     {
         moduleId = moduleIdCounter++;
         button1.OnInteract += delegate () { PressButton1(); return false; };
         button2.OnInteract += delegate () { PressButton2(); return false; };
         button3.OnInteract += delegate () { PressButton3(); return false; };
         button4.OnInteract += delegate () { PressButton4(); return false; };
     }
