bot will not call back the command processing function when receiving the command

[stay-miku]

I tried to write a simple bot program. When I sent a command to the bot, I could see on the console that the bot received the command but did not call the callback function.
code:

import asyncio
import logging


from telegram import __version__ as TG_VER

try:
    from telegram import __version_info__
except ImportError:
    __version_info__ = (0, 0, 0, 0, 0)  # type: ignore[assignment]

if __version_info__ < (20, 0, 0, "alpha", 1):
    raise RuntimeError(
        f"This example is not compatible with your current PTB version {TG_VER}. To view the "
        f"{TG_VER} version of this example, "
        f"visit https://docs.python-telegram-bot.org/en/v{TG_VER}/examples.html"
    )

from telegram import Update, InputMediaPhoto, BotCommand
from telegram.ext import Application, CommandHandler, ContextTypes, MessageHandler, filters


logger = logging.getLogger("bot")

logging.basicConfig(level=logging.DEBUG,
                    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')


do_stop_bot = False


async def stop_bot(update: Update, context: ContextTypes.DEFAULT_TYPE):
    logger.info("stop attempt")
    logger.info("stop")
    await context.bot.sendMessage(chat_id=update.effective_chat.id, text="completed")
    global do_stop_bot
    do_stop_bot = True


async def block():
    while not do_stop_bot:
        await asyncio.sleep(1)


async def run_bot(application: Application):
    application.add_handler(CommandHandler("stop_bot", stop_bot))

    # run bot
    await application.initialize()
    await application.start()
    await application.updater.start_polling(allowed_updates=Update.ALL_TYPES, read_timeout=600, write_timeout=600
                                            , pool_timeout=600, connect_timeout=600, timeout=600)

    logger.info("bot start")

    await block()

    # stop bot
    await application.updater.stop()
    await application.stop()
    await application.shutdown()

    logger.info("bot stop")


def run():

    application = Application.builder().token("api key").build()

    asyncio.run(run_bot(application))

run()

In addition, this code runs normally under python3.11 on the Windows 11, but cannot run normally on python3.9 and 3.8 on the Debian 11.

Looks like the same issue as in #3669 :) tl;dr: move application = Application.builder()… to somewhere within asyncio.run
