Re: [sphinx-doc/sphinx] ModuleNotFoundError: No module named 'sphinx.util.pycompat' (Issue #11125)
The module was deprecated at 4.0 and removed at 6.0, see https://github.com/sphinx-doc/sphinx/pull/7316/files for deprecation. See also https://www.sphinx-doc.org/en/master/search.html?q=pycompat. The import attempt does not come from Sphinx code.
