JavaFX show ImageView from other class array

there i have made Minimal Code base as passible, hope it helps as example u can use random PNG image files as you want in Class 2 in constructor BufferedImage.getSubImage is getting all needed images from only 1 file and adding every single BufferedImage converted to ImageView giving it to every array up to 32 :)

Class 1:

import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.effect.DropShadow;
import javafx.scene.effect.GaussianBlur;
import javafx.scene.effect.Glow;
import javafx.scene.layout.Pane;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.scene.text.Text;
import javafx.stage.Stage;

public class Game extends Application{
private GameMenu gameMenu;

@Override

    // nastavenie pozadia

    Pane root = new Pane();
    root.setPrefSize(1600,900);
    primaryStage.setResizable(false); // resize okna = false
    primaryStage.show(); // kebyze to nemame mame hnusne biele okraje xD

    this.gameMenu = new GameMenu();
    this.gameMenu.setVisible(true);

    root.getChildren().addAll(this.gameMenu);

    Scene scene = new Scene(root);
    primaryStage.setScene(scene);
    primaryStage.show();


} // End start

private class GameMenu extends Parent {

        btn1.setOnMouseClicked(event -> {

        });

        menu0.getChildren().addAll(btn1);
        getChildren().addAll(menu0);
    } // End Const.



} // End GameMenu

        bg.setEffect(blur);

        setAlignment(Pos.CENTER);
        setRotate(-0.5);
        getChildren().addAll(bg, this.text);

        setOnMouseEntered(event -> {
            bg.setTranslateX(10);
            this.text.setTranslateX(10);
            bg.setFill(Color.WHITE);
            this.text.setFill(Color.BLACK);
        });

        setOnMouseExited(event -> {
            bg.setTranslateX(0);
