Trying to log in with librespot.core.Session.Builder().oauth().create() throws this error:

Traceback (most recent call last):
  File "/.../librespot-python/test.py", line 2, in <module>
    session = Session.Builder().oauth(print).create()
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/.../librespot-python/librespot/core.py", line 1677, in create
    session.authenticate(self.login_credentials)
  File "/.../librespot-python/librespot/core.py", line 985, in authenticate
    self.dealer().connect()
  File "/.../librespot-python/librespot/core.py", line 481, in connect
    self.__session.tokens().get("playlist-read"),

  File "/.../librespot-python/librespot/core.py", line 2301, in get_token
    response = self._session.mercury().send_sync_json(
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/.../librespot-python/librespot/mercury.py", line 186, in send_sync_json
    raise MercuryClient.MercuryException(response)
librespot.mercury.MercuryClient.MercuryException: status: 403

It seems to happen after OAuth login, as a credentials.json file is created despite the error, and the error occurs without the OAuth callback if it's retried with the credentials.json file present.

To Reproduce
Steps to reproduce the behavior:

Run this code:

from librespot.core import Session
session = Session.Builder().oauth(print).create()

Paste the OAuth link into a browser and log in with a valid Spotify account
Watch the error happen after logging in

Expected behavior
The login is successful.

Client Information (please complete the following information):

OS: Linux Mint 22.1
Python Version: 3.12.3
Library Version: The latest version from the repo

Seeing the same with

self.session = Session.Builder().stored_file().create()

How did you solve this?

/cc @kokarare1212 as Ghost won't be able to reopen

NVM: Project dependency hick-up. Solved by:

pip uninstall librespot     
pip install git+https://github.com/kokarare1212/librespot-python@main
