ImportError: cannot import name '_request_ctx_stack' from 'flask'

🔰 I just applied a quick tutorial code to my Flask app.

# ...
app = Flask(__name__)

user_datastore = SQLAlchemySessionUserDatastore(db.session, UserModel)
security = Security(app, user_datastore)
# ...

🚫 Then this error occured:

    ...
    from flask import _request_ctx_stack
ImportError: cannot import name '_request_ctx_stack' from 'flask' (C:\myprojectpathwashere\.venv\Lib\site-packages\flask\__init__.py)

I think it is due to the version of Flask. I don't want to downgrade my Flask version, but I guess I have to.
