We just ran into a new error with the changelog part of our documentation build after the recent release of towncrier 22.12.0, which does not occur with 22.8.0. I'm trying to fix it in PlasmaPy/PlasmaPy#1850. Here's a link to the most recent build failure.

We have a file, docs/whatsnew/dev.rst, which on our main branch is:

:orphan:

.. changelog::
   :towncrier: ../../

It's referred to within a toctree in our docs/whatsnew/index.html.

After the 22.12.0 release, we starting getting this error:

/home/runner/work/PlasmaPy/PlasmaPy/docs/whatsnew/dev.rst:3: CRITICAL: 'Config' object is not subscriptable

I'm not sure if the Config object refers to Config from load.py in towncrier or sphinx.sphinx.config.Config. I'm also not sure if this is related to something peculiar to our setup, or something more general.

(We also got a new missing title error for dev.rst, which we fixed by adding a title.)

Thank you!
