Python Discord bot is not working in two days

Question

I'm trying to create a Python Discord bot. This is a simple bot but since yesterday the bot is not working; the commands do not work and Pycharm IDE is not showing any error code.

Here is my code:

import discord
from discord.ext.commands import Bot

TOKEN = "Token"

intents = discord.Intents.default()

bot = Bot(command_prefix='$', intents=intents)

@bot.command()
async def hi(ctx):
    await ctx.reply("Hello World!")

bot.run(TOKEN)
