    label = new Label(txt);
    yButton = new Button("YES");

      out.print("\033[H\033[2J");
      out.flush();
      // an ASCI code to clear the console
    out.println("Which version do you want: \n 1) JavaFX (graphical) \n 2) Java (text)?");
    String answer = input.nextLine();
    if (answer.equals("1")) {
      out.println("Please watch the output screen and click fullscreen");
      launch(args);
    } else {
      EPStore.initialize();
    }
  }
} 

note: this this happened after I added this

 txt = """

Just a thing, nothing to do with your problem. You are calling launch(args); twice. You can’t call launch method more than once in a JavaFX

public static void main(String[] args) {
    launch(args); // Calling here
    Scanner input = new Scanner(System.in);
      out.print("\033[H\033[2J");
      out.flush();
      // an ASCI code to clear the console
    out.println("Which version do you want: \n 1) JavaFX (graphical) \n 2) Java (text)?");
    String answer = input.nextLine();
    if (answer.equals("1")) {
      out.println("Please watch the output screen and click fullscreen");
      launch(args); //And calling here
    } else {
      EPStore.initialize();
    }

Also this is wrong:

@BananaPi

scene = new Scene(vbox, hbox, 600, 400);

According to docs: Scene (JavaFX 20)

The Scene class doesn’t have a constructor that takes two nodes (vbox and hbox that you are using) and two double values (like 600 and 400). So you should construct the scene taking these for account.

Something like this:

VBox vbox = new VBox();
HBox hbox = new HBox(yButton, nButton);
vbox.getChildren().addAll(label, hbox);
vbox.setSpacing(5);
vbox.setAlignment(Pos.CENTER);

Scene scene = new Scene(vbox, 600, 400);

primaryStage.setTitle("EphraimMart");
primaryStage.setScene(scene);
primaryStage.show();

About the weird letters…
I don’t remember if Replit support ASCII escape sequences. Try to comment them and run the code again. If it works it’s because Replit does not support it.
