Manim mishandling imports or import confusion

Description of bug / unexpected behavior

My file structure is as follows:

# root of git repo
.git
└── project
    ├── __init__.py
    ├── utils
    │   ├── __init__.py
    │   ├── timeline.py
    │   └── utils.py
    ├── scenarios
    │   ├── __init__.py
    │   └── basic.py

I have a Scene defined in basic.py. basic.py also has an import from timeline.py. Whether I use an absolute or relative import I get an error when running manim render:

Using: from project.utils.utils import function I get: ModuleNotFoundError: No module named 'project'

Using: from ..utils.utils import function I get: ImportError: attempted relative import with no known parent package

The behavior is the same no matter what directory I run manim render from, e.g. in either the root folder or in the /project/scenarios folder.

I'm running manim render -pql project/scenarios/basic.py AnimateScenario

What am I doing wrong here from an import perspective / why is manim causing this behavior?

Expected behavior

Expect manim render ... to run successfully with current reasonable usage of imports in my project

How to reproduce the issue

Replicate folder structure above.
