Why doesn't the transition to another scene work?

Question

Game development

Good day to all who read. The league of inepts is crying out for help
Cannot make the transition on the button to another scene. I don't understand where is the error
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class NewG : MonoBehaviour
{
public void NewGame()
{
SceneManager.LoadScene("S1");
}
}
The script was attached to the button

Answer 1

Did you put the specified scene in Scenes in Biuld?
For starters, I would like to read the error log !!!

Answer 2

1) Attach your scene in the game's build options;
2) I recommend loading levels asynchronously. Learn Coroutine in Unity.
