This code is to create a simple graphical quiz. The tkinter window always seems to crash when i press the multiple choice button on the substraction quiz. It doesnt crash on any other type of quiz. Sometimes it works when i click the multiple choice button only to crash further into the quiz. Heres the code:

Code:
import tkinter as tk
import random

def main_menu():
    clear_window()
    root.configure(bg='DodgerBlue4')

    title = tk.Label(root, text="Math Quiz", font=("Arial", 32), bg='DodgerBlue4', fg='white')
    title.pack(pady=40)

    button_frame = tk.Frame(root, bg='DodgerBlue4')
    button_frame.pack(pady=20)

    operations = [
        ("Multiplication", lambda: select_quiz_type('Multiplication'), 'red'),
        ("Addition", lambda: select_quiz_type('Addition'), 'forest green'),
        ("Subtraction", lambda: select_quiz_type('Subtraction'), 'blue'),
        ("Division", lambda: select_quiz_type('Division'), 'gold'),
    ]

    for operation, command1, color in operations:
        if command1:
            tk.Button(button_frame, text=operation, font=("Arial", 18), command=command1, bg=color, fg='white', width=12).pack(side='left', padx=20)


def clear_window():
    for widget in root.winfo_children():
        widget.destroy()

def select_quiz_type(operation):
    clear_window()
    root.configure(bg='DodgerBlue4')

    label = tk.Label(root, text=f"{operation} Quiz Type", font=("Arial", 24), bg='DodgerBlue4', fg='white')
    label.pack(pady=20)

    button_frame = tk.Frame(root, bg='DodgerBlue4')
    button_frame.pack(pady=20)

    tk.Button(button_frame, text="Multiple Choice", font=("Arial", 18), command=lambda: start_quiz(operation, "multiple_choice"), bg='gold', fg='black').pack(side='left', padx=20)
    tk.Button(button_frame, text="Submit Box", font=("Arial", 18), command=lambda: start_quiz(operation, "submit_box"), bg='gold', fg='black').pack(side='left', padx=20)

        create_quiz("Division", lambda: (random.randint(1, 100), random.randint(1, 10)), lambda x, y: x // y if y != 0 else 1, quiz_type)

I tried it on two devices and it didnt work there too. The button grays out and the tkinter window stops responding. Its weird because its only for that specific multiple choice substraction quiz
