Message event broken ( quick.db ) - quick.db

Question

So i wanna get started with quick.db for my discord.js bot. I asked someone to help me solve this issue but they seem to be unable to. So if theres anyone here that can help could you tell me whats wrong with my code
module.exports = (client) => client.on('messageCreate', async (message) => {
const prefix = [].concat(client.config.prefix);
const ms = require('ms');
if (
message.author.bot ||
!message.guild ||
!prefix.some((x) => message.content.toLowerCase().startsWith(x))
)
return;
const [cmd, ...args] = message.content
.slice(prefix
.filter((x) => message.content.toLowerCase().startsWith(x))
.sort((a, b) => b.length - a.length)[0].length
)
.trim()
.split(/ +/g);
const command =
client.commands.get(cmd.toLowerCase()) ||
client.commands.find((c) =>
[].concat(c.aliases).includes(cmd.toLowerCase())
);
if (!command) return;
const cd = client.cd.get(`${message.author.id}_${command.name}`);
const left = cd - Date.now();
if (left > 0) {
const msg = await message.channel.send(
`You are on cooldown, please wait **${ms(left)}** to use this command again`
);
return setTimeout(() => msg.delete(), left);
}
if (command.cooldown)
client.cd.set(
`${message.author.id}_${command.name}`,
Date.now() + ms(command.cooldown)
);
try {
await command.run(client, message, args);
} catch (error) {
message.channel.send(error.toString());
}
}); 
the above code is the working one but whenever i use this
module.exports = (client) => client.on('messageCreate', async (message) => {
const ms = require('ms');
const { QuickDB } = require('quick.db');
const db = new QuickDB();
const prefix = db.get(`newprefix_${message.guild.id}`) || config.prefix
if (!prefix) return; 
if (!message.content.startsWith(prefix) || message.author.bot) return;
const [cmd, ...args] = message.content
.slice(prefix
.filter((x) => message.content.toLowerCase().startsWith(x))
.sort((a, b) => b.length - a.length)[0].length
)
.trim()
.split(/ +/g);
const command =
client.commands.get(cmd.toLowerCase()) ||
client.commands.find((c) =>
[].concat(c.aliases).includes(cmd.toLowerCase())
);
if (!command) return;
const cd = client.cd.get(`${message.author.id}_${command.name}`);
const left = cd - Date.now();
if (left > 0) {
const msg = await message.channel.send(
`You are on cooldown, please wait **${ms(left)}** to use this command again`
);
return setTimeout(() => msg.delete(), left);
}
if (command.cooldown)
client.cd.set(
`${message.author.id}_${command.name}`,
Date.now() + ms(command.cooldown)
);
try {
await command.run(client, message, args);
} catch (error) {
message.channel.send(error.toString());
}
});  
it doesn't work, meaning my bot doesn't reply
