Please look at this thread Database is locked even after deleting social.db and restarting app.py. Check the models.py

The User model should have a classmethod that uses the transaction method.

    @classmethod
    def create_user(cls, username, email, password, admin=False):
        try:
            with DATABASE.transaction():  # <-- verify this line exists
                cls.create(
                    username=username,
                    email=email,
                    password=generate_password_hash(password),
                    is_admin=admin)
        except IntegrityError:
            raise ValueError("User already exists")

You may need to delete your database file before restarting.
