Reproducer

1. Build Sphinx document from https://gitlab.com/mcepl/petunia_dursley/-/commit/832c32cc923dcf43954e34a76c5b296e9a3ae7dd
2. Run python3 -msphinx -vvv -N . _build
3. See the above output
4. List of all packages installed on the system

Expectation

Build happens without any problems (as it does with the default alabaster theme).

Code of Conduct

• I agree to follow the Code of Conduct.

[pradyunsg]

I can't reproduce this. This is probably related to how Furo has been repackaged for your environment. Please provide the output of python3 -m pip list as I requested earlier.
