I am creating an app that generates a schedule for my school. Here is the python code for it:

import tkinter as tk
from tkinter import ttk
import os
import json
import logging
import datetime
import sys

logging.basicConfig(level=logging.DEBUG, filename='app.log', filemode='w',
                    format='%(name)s - %(levelname)s - %(message)s')

if getattr(sys, 'frozen', False):
    application_path = os.path.dirname(sys.executable)
else:
    application_path = os.path.dirname(__file__)
  
PREFERENCES_FILE = os.path.join(application_path, "user_preferences.json")

def save_preferences(data):
    try:
        with open(PREFERENCES_FILE, 'w') as f:
            json.dump(data, f)
        logging.info("Preferences saved successfully.")
    except Exception as e:
        logging.error(f"Failed to save preferences: {e}")
      
def load_preferences():
    try:
        if os.path.exists(PREFERENCES_FILE):
            with open(PREFERENCES_FILE, 'r') as f:
                return json.load(f)
    except Exception as e:
        logging.error(f"Error reading preferences: {e}")
    return None

def delete_preferences():
    try:
        if os.path.exists(PREFERENCES_FILE):
            os.remove(PREFERENCES_FILE)
            logging.info("Preferences deleted successfully.")
    except Exception as e:
        logging.error(f"Failed to delete preferences: {e}")
      
def show_schedule(day, preferences):
    schedule = preferences['schedule']
    day_schedule = schedule.get(day, [])
    schedule_text = f"Schedule for {day}:n"
    for time_range, subject_key in day_schedule:
        subject = preferences['subjects'].get(subject_key, "Free")
        schedule_text += f"{time_range} - {subject}n"
    schedule_label.config(text=schedule_text)

I tried to create the program on my Mac using this command:

pyinstaller --windowed --onefile --icon=/Users/jacob/ icon.iconset/857457.icns --name="School Schedule App" /Users/jacob/School_Schedule_App.py

When I tried to open the app by double clicking it, nothing happened. However, if I went into the package contents and then the MacOS folder, running the shell script would open the app and make it run normally. Why is this, and how can I make it so that it runs just by opening the app normally?

Thank you, and if you have any follow-up questions, let me know, and I will do my best to answer them.
