Description of Problem / Question / Details

Hi, I made an error while running the Demo_Menus.py and the menu at the top cannot be displayed. The running result is as follows:

Paste your code here

#!/usr/bin/env python
import PySimpleGUI as sg
"""
Demonstration of MENUS!
How do menus work? Like buttons is how.
Check out the variable menu_def for a hint on how to
define menus

window.close()

test_menus()

Start by reproducing the reported behavior on macOS with Python 3.8 using Demo_Menus.py, entering through test_menus() and its sg.Menu definition. Inspect the menu creation and capture the actual runtime error or display behavior, since the issue does not include the screenshot or error text. Done means the demo's top menu is displayed and usable without changing its intended menu entries.
