Telegram Bot Error Code 409：单实例运行仍触发冲突报错求助

运行以下代码时，尽管已确认只有一个本地进程调用infinity_polling()，仍触发Error Code 409报错。查阅相关帖子后，未找到匹配场景或有效解决方案。

环境信息 #

• MacOS Ventura 13.5
• VSCode 1.81.1 (Universal)
• 项目使用pyenv 2.3.24管理Python 3.9.12
• pip3已安装pyTelegramBotAPI 4.13.0和telebot 0.0.5，同事仅安装pyTelegramBot 4.9.0即可正常运行
• pip版本23.2.1
• 团队其他成员在不同机器运行同款代码无问题

已尝试的解决方法 #

• 重启电脑
• 在活动监视器中终止所有Python和VSCode进程
• 删除本地仓库并重新克隆
• 卸载并重装pyTelegramBotAPI和telebot
• 注释循环导入语句（TelegramBot.py→helper.py→fileNo2.py→TelegramBot.py），无改善
• 改用同事的pyTelegramBotAPI 4.9.0版本并卸载telebot，无效
• 在bot.infinity_polling()前添加bot.remove_webhook()调用，无效

希望避免的操作 #

• 不想创建新的token或Telegram Bot，这会给团队协作带来困扰

疑问 #

1. 多实例运行问题仅存在于本地吗？即不同机器同时调用getUpdates是否允许，同一机器多个进程则不行？
2. 重启电脑后为何仍有其他进程调用bot.infinity_polling()？重启不是会终止所有进程吗？

代码 #

import telebot
import emoji
import sys
import Helpers.helper as helper

TOKEN = '*************************************'

bot = telebot.TeleBot(TOKEN, parse_mode=None)

@bot.message_handler(commands=['help'])
def send_welcome(message):
    bot.reply_to(message, "// List of commands for the bot")

if __name__ == '__main__':
    try:
        print("before call to IP")
        bot.infinity_polling()
        print("after call to IP")
    except (KeyboardInterrupt, SystemExit):
        pass

终端输出（按Ctrl-C终止） #
