    ‘_request_ctx_stack’ is deprecated and was removed in Flask 2.3. Chances are high that some of the packages you are relying on make use of it. Downgrading to a lower version may fix the issue. Flask versions >= 2.2 or lower may work fine.

    If you are using flask_opentracing, it made use of this deprecated private name. The latest (and last) 2.0.0 version of flask_opentracing fixes this. flask_login also fixed this in a recent release.
