Create a GuiScreen just before the MainMenu, take an Input via GuiTextField, and return to the main Menu

Effectively, here is the code I've currently been working with:

Main Class:

@SubscribeEvent
public void onGuiScreen(GuiOpenEvent event) {
  InputMenu menu;
  if (event.gui instanceof GuiMainMenu) {
    menu = new InputMenu(event.gui);
    event.gui = menu;
  }
}

InputMenu Class:

public class InputMenu extends GuiScreen {
  private GuiTextField inputField;
  private GuiScreen previousScreen;
  public InputMenu(GuiScreen previousScreen) {
    this.previousScreen = previousScreen; // save the main menu to return to later
  }
  
  @Override
  public void initGui() {
    inputField = new GuiTextField(-1, fontRendererObj ...);
  }
  
  @Override
  public void drawScreen(int mouseX, int mouseY, float partialTicks) {
    inputField.drawTextBox();
    inputField.setFocused(true);
  }
  
  @Override
  public void updateScreen() {
    inputField.updateCursorCounter();
  }
  
  @Override
  protected void keyTyped(char typedChar, int keyCode) throws IOException {
    if (keyCode == Keyboard.KEY_RETURN) {
      // go back to menu
      HandleInput();
      mc.displayGuiScreen(previousScreen); // doesn't work
    }
    
    inputField.textboxKeyTyped(typedChar, keyCode);
  }
}

This isn't returning to the main menu, but is instead staying on the InputMenu screen, and only resetting the textField to empty characters upon pressing enter. I can't get it to return, even though I have set the mc.displayGuiScreen correctly. What might be the issue?

EDIT: SOLVED

The issue was that GuiOpenEvent got called when I tried to go back to the MainMenu, which, according to my old conditionals, would just display the InputMenu again. Adding a boolean fixed this, by checking if the user has already seen this menu before
