I am trying to build a GUI with PySimpleGUI for the first time and am struggling with the layout reuse rules.
The overall aim of the script will be to make entering data into a CSV table easier for users. For this purpose, the users will be able to enter data into a form, submit the data, and decide if they want to add another data set or exit.
I have tried to work with nested functions but am constantly breaking the script because I am supposed to use a new layout for each window. I have defined 3 different windows with their own layouts so far:
window1 = main window where data can be added
window2 = window with error notification
window3 = window opening after SUBMIT, asking users if they want to continue
In addition, I am trying to call the function for window1 again if users decide to add more data (repeatGUI()), but this is not permitted.
I am aware that there are other issues in the script, too, but I would mainly appreciate some input on the layout-reuse issue. What is the proper way of opening an input window multiple times?

Following way show that you use the variable layout1 as layout of sg.Window again and again, none of element in layout1 initialized after 1st time using.
while True: # The Event Loop
event1, values1 = window1.Layout(layout1).Read()
...
Following code preferred,
window1 = sg.Window('Title1', layout1, finalize=True)
while True:
event1, values1 = window1.read()
...
or
def make_window1():
layout = [
[sg.Text('Please enter a new factoid:')],
....
]
return sg.Window('Title1', layout, finalized=True)
window1 = make_window1()
while True:
event1, values1 = window1.read()
...
