Thanks Brian!

Though for some reason this gives a 404 Not Found error.  But it
doesn't matter, as I think the snippet quoted below is enough.

OK, this is strange.  pkg_resources is picking up an old or broken
version of python_lsp_black-*.egg-info.  Could you try

ls -R /usr/local/lib/python3.11/dist-packages/python_lsp_black*
ls -R /usr/local/lib/python3.11/dist-packages/pylsp_black*

ls -R /usr/lib/python3/dist-packages/python_lsp_black*
ls -R /usr/lib/python3/dist-packages/pylsp_black*

ls -R /usr/lib/python3.11/dist-packages/python_lsp_black*
ls -R /usr/lib/python3.11/dist-packages/pylsp_black*

One of these pairs of commands is likely to identify the culprit!

Best wishes,
