Error:Sleep for 1.000000 seconds and try again… (tryings = 0, bot id = 7011809806)
Failed to fetch updates – TelegramConflictError: Telegram server says – Conflict: terminated by other getUpdates request; make sure that only one bot instance is running

Code:

import os
from aiogram import Bot, Dispatcher, F
import asyncio
from handlers import start_handler, test_handler
from keyboard import get_reply_keyboard
from data.Cities import city_handler, city_info_handler

TOKEN = "hide"

async def start():
    bot = Bot(token=TOKEN)
    dp = Dispatcher()

    dp.message.register(city_handler, F.text=='Города????')
    #города
    dp.callback_query.register(city_info_handler)

    await dp.start_polling(bot)
    
if __name__ == "__main__":
    asyncio.run(start())

I tried changing the code, but nothing changed.
