初始化热键时，侦听器回调中未处理的异常

Question

我是python和编写热键脚本的新手。我正在编写一个热键脚本来帮助自动化部分工作。我已经编写了脚本，并且似乎不需要长if语句就可以工作。现在它位于if语句中，它会引发错误。错误是侦听器回调中的未处理异常。是什么导致此错误？
脚本是：

   from pynput import keyboard
import datetime
import AdvancedHTMLParser

# The key combinations to check
COMBINATIONS = [
    {keyboard.Key.ctrl_l, keyboard.Key.shift, keyboard.KeyCode(char='c')},
    {keyboard.Key.ctrl_r, keyboard.Key.shift, keyboard.KeyCode(char='c')},
    {keyboard.Key.ctrl_l, keyboard.Key.shift, keyboard.KeyCode(char='x')},
    {keyboard.Key.ctrl_r, keyboard.Key.shift, keyboard.KeyCode(char='x')},
    {keyboard.Key.ctrl_l, keyboard.Key.shift, keyboard.KeyCode(char='z')},
    {keyboard.Key.ctrl_r, keyboard.Key.shift, keyboard.KeyCode(char='z')},
    {keyboard.Key.ctrl_l, keyboard.Key.shift, keyboard.KeyCode(char='v')},
    {keyboard.Key.ctrl_r, keyboard.Key.shift, keyboard.KeyCode(char='v')},
    {keyboard.Key.ctrl_l, keyboard.Key.shift, keyboard.KeyCode(char='b')},
    {keyboard.Key.ctrl_r, keyboard.Key.shift, keyboard.KeyCode(char='b')},
    {keyboard.Key.ctrl_l, keyboard.Key.shift, keyboard.KeyCode(char='e')},
    {keyboard.Key.ctrl_r, keyboard.Key.shift, keyboard.KeyCode(char='e')},
    {keyboard.Key.ctrl_l, keyboard.Key.shift, keyboard.KeyCode(char='d')},
    {keyboard.Key.ctrl_r, keyboard.Key.shift, keyboard.KeyCode(char='d')},
    {keyboard.Key.ctrl_l, keyboard.Key.shift, keyboard.KeyCode(char='v')},
    {keyboard.Key.ctrl_r, keyboard.Key.shift, keyboard.KeyCode(char='v')},
    {keyboard.Key.esc}
]

with keyboard.Listener(on_press=on_press, on_release=on_release) as listener:
    listener.join()
