Object has no problem finding instance in editor. However in build it does.

Hi, hope u don't run into this problem.

I'm working on this project, and when I make a build, the movement stops working.
The movement is a basic AddForce(), but works in a State Machine architecture (since im a dumb dumb, I only started making test builds close to the "deadline").
After doing some debugging, I found out it is able to find the instance to Log in the console, but does not find it to check the bool. As u can see below:

  public override void Update(PlayerController player)
 {
     Debug.Log("PLAYER CONTROLLER: " + player);
     if (player._input.inputGiven)
     {
         Debug.Log("PLAYER CONTROLLER 2: " + player);
         player.TransitionToState(player.moveState);
     }
 }

I already tried lots of stuff, but without any reasonable progress.
Below u can see the console in editor, and in the build.

ALSO im not the best coder, so please, even tho I checked my code coutless times u can check it below, I choose only to show parts related to the issue for the readers sake.

Player Controller:

  public class PlayerController : MonoBehaviour
 {
     //--------------------STATE MACHINE------------------------------------
     PlayerBaseState currentState;

     public readonly PlayerIdleState idleState = new PlayerIdleState();      //
     public readonly PlayerMoveState moveState = new PlayerMoveState();      // SO PURFECT
     public readonly PlayerDeadState deadState = new PlayerDeadState();      //    W0W
     public readonly PlayerDashState dashState = new PlayerDashState();      //
     public readonly PlayerGrabState grabState = new PlayerGrabState();      //
     //--------------------STATE MACHINE------------------------------------

     [HideInInspector] public InputHandler _input;

(...)

     private void Awake()
     {
         _input = InputHandler.Instance;
         rigidbody = GetComponent<Rigidbody>();

         enemyLayer = LayerMask.GetMask("Enemies");
         minDistance = detectRange;

         currentHp = maxHp;

         engageDrag = rigidbody.drag;//               Set Moving Drag
         engageAngularDrag = rigidbody.angularDrag;//
         engageMass = rigidbody.mass;
     }

     void Start()
     {
         TransitionToState(idleState);//default state
     }

     void Update()
     {
         currentState.Update(this); 
     }

     private void OnCollisionEnter(Collision collision)
     {
         currentState.OnCollisionEnter(this);
     }

     private void FixedUpdate()
     {
         currentState.FixedUpdate(this);
     }

     public void TransitionToState (PlayerBaseState state)
     {
         currentState = state;
         currentState.EnterState(this);
     }

(...)
BaseState:

  public abstract class PlayerBaseState
 {
     public abstract void EnterState(PlayerController player);

     public abstract void Update(PlayerController player);

     public abstract void FixedUpdate(PlayerController player);

     public abstract void OnCollisionEnter(PlayerController player);
 }

Player Idle State:

  public class PlayerIdleState : PlayerBaseState
 {
     public override void EnterState(PlayerController player)
     {
     }

     public override void OnCollisionEnter(PlayerController player)
     {
 
     }

     public override void Update(PlayerController player)
     {
         Debug.Log("PLAYER CONTROLLER: " + player);
         if (player._input.inputGiven)
         {
             Debug.Log("INPUt 2: " + player);
             player.TransitionToState(player.moveState);
         }
     }

     public override void FixedUpdate(PlayerController player)
     {
         player.CheckForEnemies();
     }
 }

Thanks in advance :D
