Python code blocks not rendering with readthedocs and sphinx

I'm building docs for a python project using Sphinx and readthedocs. For some reason, the code blocks aren't rendering after building the docs, and inline code (marked with backticks) appears italic. I've checked the raw build, there was a warning that the exomagpy module couldn't be found which I resolved by changing ".." to "../" in the os.path.abspath() part of conf.py, this didn't appear to change anything in the docs. There was a similar question here on stackoverflow, I tried the solution but it didn't change.

The raw build can be found here: https://readthedocs.org/api/v2/build/17574729.txt

Here is the link to the github page: https://github.com/quasoph/exomagpy/tree/Develop

The repo is structured like so:

>.vscode
>build/lib/exomagpy

>docs
   >conf.py
   >rst files (.rst)
   >makefile
   >make.bat

>exomagpy.egg-info

>exomagpy
   >__init__.py
   >module files (.py)

>.readthedocs.yml
>requirements.txt
>setup.py

Here are my files:

conf.py

import os
import sys
sys.path.insert(0, os.path.abspath("../"))

# project info

project = "exomagpy"
root_doc = "index"
release = "1.3.0"

# general config

extensions = ["sphinx.ext.autodoc","sphinx.ext.napoleon","sphinx.ext.autosummary"
]

templates_path = ['_templates']
exclude_patterns = ['_build', 'Thumbs.db', '.DS_Store']

# html options

html_theme = 'sphinx_rtd_theme'
html_static_path = []

.readthedocs.yml

    url = "link",
    description = "description",
    packages = find_packages()
)

Any help really appreciated, please let me know if more information is needed.
