Flask app won't deploy on ElasticBeanstalk

Question

I'm deploying a flask app on AWS ElasticBeanstalk. I created a new venv from terminal and used eb init to create the instance of the application in AWS. I then used eb create APPNAME-env to make an environment for the application. On AWS, the health of the site is listed as "OK". However, when I go to the URL, it is a blank white page with no HTML. I looked at the logs, and in web.stdout.log, there were several errors. All of them were the same Traceback, from importlib.import_module(). Each error said ModuleNotFoundError: No module named 'application'. I renamed my main file to application.py so there would be a module named application, and created a new app instance and new environment. The error persists and the page remains blank. Why does it want a module named application, and why isn't it running correctly?

Here's some additional info:

All the Tracebacks were from load_wsgi(), by the way.

File structure:

code of application.py:
