Discord bot 'interactionCreate' listener responded a few times, then quit responding without me changing the code

OS Windows 11

I was following the tutorial from the discord docs and building slash commands for my bot. I was able to register the commands and get the success message, then /ping the bot and get a response. I committed and walked away. A few hours later I come back to start building more commands and the bot doesn't respond to /ping anymore. In fact, this block of code is not being reached at all:

client.on('interactionCreate', async interaction => {
    if (!interaction.isCommand()) return;
    const command = client.commands.get(interaction.commandName);
    if (!command) return;
    try {
        await command.execute(interaction);
    } catch (error) {
        console.error(error);
        await interaction.reply({ content: 'There was an error while executing this command!', ephemeral: true });
    }
});

I've tried:

• reinstall npm
• reinstall discord.js
• kick the bot and redo the scopes and permissions (not changing them)
• wait a few hours for the api to catch up registering the slash commands
• tried interaction instead of interactionCreate

Notes:

• I am using these intents : FLAGS.GUILDS, FLAGS.GUILD_MESSAGES, FLAGS.GUILD_EMOJIS_AND_STICKERS

• I am using .mjs files for the commands, and import() syntax to register them. It was in a working state with those things when I left it. I've also tried reverting to require since the docs use that but that did not change anything.

• I did once get the error described here but it went away and I now see Successfully registered application commands when I deploy the commands.

• UPDATE:

• The require syntax for importing files and registering events and commands seems to work. ES6 modules do not seem to let me register commands.
