There is a programmable error in your configuration file:
Traceback (most recent call last):

ImportError: cannot import name 'create_warning' from 'myst_parser.mdit_to_docutils.sphinx_' (/opt/hostedtoolcache/Python/3.9.18/x64/lib/python3.9/site-packages/myst_parser/mdit_to_docutils/sphinx_.py)
Maybe an issue with the Sphinx version?
