(node:630) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 message listeners added to [Client]. Use emitter.setMaxListeners() to increase limit
Judging from the warning message, 11 message listeners added to [Client], maybe your code is working as designed? How many listeners did you think you added? It looks like its only a warning rather than a runtime error.
Is your project having a problem, and if so what is it doing vs what you expected it to do?
Or is there a chance that you are repeatedly instantiating part of your bot in a loop or a lightweight function without realising it?
It might be helpful to add in something like console.trace("Listener attached") inside your client.on blocks so you can see in your logs when and why they are being called.
I doubt your source code is that sensitive unless you’ve put your discord keys in there (tip, put them in .env instead) so maybe you could share some snippets of it.
