Unable to debug Flask app in Visual Studio Code

I have a currently working flask app. I want to debug it in Visual Studio Code. I keep hitting errors that I can't google my way out of. I have gone through How do I debug Flask App in VS Code and the video, it did not solve my inability to debug. I have also copied the instructions from https://code.visualstudio.com/docs/python/tutorial-flask and I was able to debug in a new example file! But I can't translate this success to my current project that I cannot debug. The main error line seems to be ModuleNotFoundError: No module named 'app'. Or perhaps that isn't the error, I can't tell. If any further information is needed please state so, I don't want to plaster endless error messages.

Also my launch.json is correctly copied/formatted based off both the visual studio code tutorial and from Miguel's(the first link). The end goal is to step through the visual studio code debugger successfully.

I changed my "env":{"FLASK_APP"= LOCATION}

LOCATION is the entire source path to your root app.py.

AKA C:\Users\Folder\Folder\app.py but use \\ instead of \ when answering in code.
