Python app built by PyInstaller crashes when exit button is clicked

I'm using the codes below in a run.py file from PySimpleGUI cookbook for the GUI of my Python app. The GUI works normally when I started the run.py file from PyCharms. However, when I build this into a one file, windowed app with PyInstaller, I get an app crashed error message everytime I close the app with the Exit button on the GUI. I tried to build the app as one file, console app and there wasn't any issue. Has anyone seen this problem before and how to resolve this issue?

def main():
    sg.theme('Tan Blue')

    layout = [
        [sg.Text('Root Path:', size=(15, 1)), sg.InputText(root_path), sg.FolderBrowse()],
        [sg.Text('Date:', size=(15, 1)), sg.InputText(datetime.today().strftime('%Y-%m-%d %H:%M:%S')),
         sg.CalendarButton('Choose Date', target=(1, 1), key='date')],
        [sg.Output(size=(80, 15), key = '_output_')],
        [sg.Button('Run'), sg.Button('Exit'), sg.Button('Clear')]
    ]

    window = sg.Window('App name', layout)

    while True: # Event Loop
        event, values = window.Read()
        if event in (None, 'Exit'):
            break
        elif event == 'Run':
            runScript(values)
            window.Refresh()
        if event == 'Clear':
            window.FindElement('_output_').Update('')
    window.close()


def runScript(values):
    """ run shell command
    @param cmd: command to execute
    @param timeout: timeout for command execution
    @param window: the PySimpleGUI window that the output is going to (needed to do refresh on)
    @return: (return code from command, command output)
    """

Does runScript() open a Window which a user can Exit from? If so, it may be that the original window from main() does not close. You need to return a value that will close each window that has been called in the chain.

def main():
sg.theme('Tan Blue')

layout = [
    [sg.Text('Root Path:', size=(15, 1)), sg.InputText(root_path), sg.FolderBrowse()],
    [sg.Text('Date:', size=(15, 1)), sg.InputText(datetime.today().strftime('%Y-%m-%d %H:%M:%S')),
     sg.CalendarButton('Choose Date', target=(1, 1), key='date')],
    [sg.Output(size=(80, 15), key = '_output_')],
    [sg.Button('Run'), sg.Button('Exit'), sg.Button('Clear')]
]

window = sg.Window('App name', layout)

while True: # Event Loop
    event, values = window.Read()
    if event in (None, 'Exit'):
        break
    elif event == 'Run':
        to_continue = runScript(values) # Add a check if exit pressed
        if not to_continue:
            break
        window.Refresh()
    if event == 'Clear':
        window.FindElement('_output_').Update('')
window.close()

def runScript(values):

...
 while True: # Event Loop
    event, values = window.Read()
    if event in (None, 'Exit'):
        to_continue = False
        window.close()
        return to_continue

Note that you would need to return to_continue as True if the user does not exit the window but instead the function finishes normally.
