How to close current scene and display another one in AS3?

Question

ActionScript

In general, I wrote the code for the mini-game.
I need to make it so that after the game ends, the scene with the game closes and the scene with the main menu opens.
This is the part of the code where the game ends, in class N

var GoMenu:Main = new Main(); 
addChild(GoMenu); //Добавляю сцену с меню
          
GoMenu.closePlay(); //Вызываю функцию с закрытием сцены игры из Main класса

This is, respectively, the closePlay function itself in the Main class

public function closePlay():void
{
  GoPlay2 = new SceneGame();
  removeChild(GoPlay2); //Пытаюсь закрыть сцену с игрой
}

But alas, with this code, the launch just crashes,

screen

Like I haven't tried before...
