Flask debugging will not run

I'm going to skip the expected and actual behaviour, because I'm pretty sure there is just something wrong with my machine all of the sudden, because this exact configuration works 30 minutes ago.

I run the debugger, I see it launch, and then it just falls back to the shell silently. Nothing in the debug console, nothing in output, nothing in problems.

Maybe someone has had this issue before

    ]
}

And I do have an app.py in the root that is the flask app
