Telebot API after separation, handlers don't work

When assembling the code in a single file, everything works. I think there is a mistake in importing or launching the bot.

import asyncio
from telebot.async_telebot import AsyncTeleBot
from src.config import Config
from src.keyboards import goods_keyboard

bot = AsyncTeleBot(token=Config.token)

@bot.message_handler(commands=['start'])
async def send_welcome(message):
    kb = goods_keyboard({"Заказать товар": 'categories', "Корзина": 'cart', "Настройки": 'settings'})
    await bot.send_message(message.chat.id, "Добро пожаловать на Вкусную Ферму!", reply_markup=kb)

async def main():
    await bot.polling()

if __name__ == "__main__":
    try:
        asyncio.run(main())
    except (KeyboardInterrupt, SystemExit):
        print("Bot stopped!")

In this case command 'start' will work. But other code from files 'categories.py' or 'callbacks.py' didn't work...

from src.bot import bot
from src.keyboards import goods_keyboard


@bot.message_handler(commands=['categories'])
async def send_categories(message):
    kb_text = {'Мясо': 'https://www.youtube.com/', 'Мясная продукция': 'https://www.youtube.com/',
               'Назад': 'back'}
    kb = goods_keyboard(kb_text)
    await bot.send_message(message.chat.id, "Выберите категорию", reply_markup=kb)
