You are right. The traceback is indeed different but more similar to 
this one, probably: https://github.com/pypa/setuptools/issues/3273

I have tried to make an empty .dist-info dir and got the very similar 
result to yours.

The following command may help to locate the actual offending package:

strace -eopenat python -c "from importlib.metadata import entry_points; 
print(entry_points(group='sphinx.builders'))"
