First of all, never show a token of your bot, or try to change it later.
Second of all:
Try using this. Since the new updated version of discord.js, like version ^13.0, you have to specify client intents:
const { Client, Intents } = require('discord.js');
const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] });
And obviously, put client.login(TOKEN)
at the very bottom.
