Python可执行文件会弹出GUI，但按钮不起作用，CMD也会弹出

Question

所以我创建了一个简单的程序，通过CMD关闭我的电脑。它在Thonny中都能正常工作，但在使其成为可执行文件后就不起作用了。当我打开可执行文件时，GUI会弹出，按下一个按钮后，一个新的GUI会弹出一个空的CMD

以下是完整的代码：

import tkinter as tk
import tkinter
from tkinter import *
from tkinter import ttk
from tkinter import font
from tkinter.ttk import *
import os
import time

def cancel():
    os.system("shutdown -a")
    textVar.set("Shutdown cancelled")
    
def shutdown():
    hourSel = hourCondition.get()
    if hourSel == 3600:
        textVar.set("Computer will shut down in 1 hour!")
        os.system("shutdown /s /t 3600")
    if hourSel == 7200:
        os.system("shutdown /s /t 7200")
        textVar.set("Computer will shut down in 2 hours!")
    if hourSel == 10800:
        os.system("shutdown /s /t 10800")
        textVar.set("Computer will shut down in 3 hours!")
    if hourSel == 14400:
        os.system("shutdown /s /t 14400")
        textVar.set("Computer will shut down in 4 hours!")
        textVar.set("Computer will shut down in 4 hours!")
    if hourSel == 0:
  
        try:
            
            val = int(value.get())
            seconds2Minutes = round(val * 0.016666667,2)
            if val > 0:
                textVar.set("Computer will shut down in " + str(seconds2Minutes) + " min")
                os.system("shutdown /s /t " + str(val))
            if val < 0:
                textVar.set("Choose correct value!")
        except ValueError:
            textVar.set("Choose correct value!")

图片说明： 下面的关机窗口是最初打开的窗口（可执行），当单击“关机”或“取消关机”时，新的关机（重复）窗口将打开，并显示空CMD。它应该在选定的时间关闭计算机。下面的窗口显示“无响应”，你知道我做错了什么吗？我使用pyinstaller--onefile-w命令生成一个可执行文件。
