Trying to set `/language` command that completely changes language of a bot but app is not respondin

const { SlashCommandBuilder, PermissionFlagsBits } = require('discord.js');
const fs = require('fs');
const restartBot = require('../../utils/restart-bot');
const { language } = require('../../config.json'); // Fetch language key from config.json
const languageSetting = require(`../../resources/languages/${language}.json`) ; // Fetch language based text responses

module.exports = {
    data: new SlashCommandBuilder()
        .setName(`${languageSetting.language_name}`)
        .setDescription(`${languageSetting.language_desc}`)
        .addStringOption(option =>
            option.setName('choose_language')
                .setDescription(`${languageSetting.language_optdesc}`)
                .setRequired(true)
                .addChoices(
                    { name: 'English', value: 'eng' },
                    { name: 'Polski', value: 'pl' }
                )
        ),
    category: 'admin',
    async execute(interaction) {

        const interactionUserPermissions = interaction.member.permissions;

        if(interactionUserPermissions.has(PermissionFlagsBits.Administrator) || interactionUserPermissions.has(PermissionFlagsBits.ManageGuild) || interaction.member.id == process.env.BOT_DEVELOPER){
