[Bug] Python Function V1 apps - Exception: ModuleNotFoundError: No module named '__app__.XXX'. Cannot find module.

[YunchuWang]

Expected Behavior

Python Function Apps using V1 programming model that are:

• Import modules from right paths following https://learn.microsoft.com/en-us/azure/azure-functions/functions-reference-python?tabs=asgi%2Capplication-level&pivots=python-mode-configuration#import-behavior
• Not defining app as a module explicitly in your function app or importing app(.xxx.yy) module from dependency packages. should run without seeing this issue in production.

Actual Behavior

It is reported from customers Exception: ModuleNotFoundError: No module named 'app.XXX'. Cannot find module. gets raised during customers' v1 python apps function loading time intermittently and restarting the app will resolve the error. We have trouble reproducing it and can't confirm at this moment if this is a customer code issue or platform issue.
