That might well be a consequence of your action above, which would
support the notion of picking up an old python2 version. (Linux's
2.18.2 from the LP website appears to use 2.4.5, whereas Debian
buster's system version is 2.7.16).

Bear in mind I don't know what the top of the LP installation
directory structure looks like on windows, only on linux.
I have no way of checking, either, because the windows download
(I assume it's "mingw") is a inscrutable exe file, as opposed to
a shell script followed by a standard compressed tar archive.

All I can say is that if you're running lilypond-book, juggling
calls to LP, Python and TeX, it's probably important to get all
the PATHs and file associations sorted out. You may need the
help of someone who runs a more similar system.

Cheers,
David.
