AttributeError: module 'bcrypt' has no attribute '__about__' with new 4.1.1 version

#Why
При авторизации возникает ошибка в логах, которая ни на что не влияет:
AttributeError: module 'bcrypt' has no attribute '__about__' with new 4.1.1 version
Ссылка на обсуждение ошибки

Причина:

• This is an issue with how passlib attempts to read a version (for logging only) and fails because it's loading modules that no longer exist in bcrypt 4.1.x.
• passlib seems to be abandoned and the new bcrypt doesn't work with it.

#How to do

• Предложено либо даунгрейдить bcrypt до Needs to force bcrypt==4.0.1 to keep using passli
• Поскольку это warning, можно его "заглушить" в настройках логгера:
  As the OP indicates here, passlib will work with latest bcrypt, it simply emits a warning. You should be able to silence that warning with a logging configuration.
  logging.getLogger('passlib').setLevel(logging.ERROR)
• Либо отказаться от passlib совсем, заимствовав требуемые методы:

I resolved it by removing the passlib module and simply using the bcrypt directly for hashing and verification :

import bcrypt

# Hash a password using bcrypt
def hash_password(password):
    pwd_bytes = password.encode('utf-8')
    salt = bcrypt.gensalt()
    hashed_password = bcrypt.hashpw(password=pwd_bytes, salt=salt)
    return hashed_password

# Check if the provided password matches the stored password (hashed)
def verify_password(plain_password, hashed_password):
    password_byte_enc = plain_password.encode('utf-8')
    return bcrypt.checkpw(password = password_byte_enc , hashed_password = hashed_password)

• Поскольку у нас используется FastApi Users, необходимо проверить можно ли безболезненно отказаться от passlib
