EDIT:

The problem is that i cant narrow it down. but this is my main() and even that doesnt start:

import glob
import time

import PySimpleGUI as sg
from PIL import Image, ImageTk

    def main():
        elements = [
            [sg.Image(key="originalbild"), sg.Image(key="ergebnisbild")],
            [
                sg.Text("Bildordner: "),
                sg.Input(size=(25, 1), enable_events=True, key="Ordner gewaehlt"),
                sg.FolderBrowse(button_text="Durchsuchen"),
            ],
            [
                sg.Button("Vorheriges Bild"),
                sg.Button("Naechstes Bild")
            ]
        ]
    
        window = sg.Window("CHAP", elements, size=(1000, 475), element_justification='c')
        images = []
        location = 0
    
        while True:
            event, values = window.read()
            if event == "Exit" or event == sg.WIN_CLOSED:
                break
    
            if event == "Ordner gewaehlt":
                images = search_images(values["Ordner gewaehlt"])
                if images:
                    load_image(images[0], window)
                    location = 0
    
            if event == "Naechstes Bild" and images:
                if location == len(images) - 1:
                    location = 0
                else:
                    location += 1
                load_image(images[location], window)
    
            if event == "Vorheriges Bild" and images:
                if location == 0:
                    location = len(images) - 1
                else:
                    location -= 1
                load_image(images[location], window)
    
        window.close()
    
    if __name__ == "__main__":
        main()

Maybe you can help me with this. The line of code where it occurs seems to be: if event == "Exit" or event == sg.WIN_CLOSED: i used the debugging mode and went step by step

Answer 1

i used a 'ß' instead of 'ss'
