Python / Ошибки в библиотеке Telebot. Ошибка в телеботе

Знаю эту ошибку, у всех она проявляется по разному, но в моем случае, я даже не знаю куда деваться, и почему она происходит я не знаю. Я выложу мой код телебота, он легкий, маленький, но очень "лагучий"

bot = telebot.TeleBot("Token")


os.chdir("C:\\Users\\SDUND\\Downloads\\Python Programer\\TeleBot - Spooky Monkey\\Spooky Stickers")

sticker_hello = open('hello.webp', 'rb')
sticker_shutdown = open('shutdown.webp', 'rb')
sticker_hack = open('hack.tgs', 'rb')
sticker_helper = open('helper.tgs', 'rb')

print("Folders and files: ", os.listdir())


def exitmode():
    key = input(">> ")
    if key == "zxcv":
        print("[ Shutdown ]")

Она также проявляется в других местах кода, но все же я бы хотел узнать, что за червь мешает работе. Спасибо за помощь!
