Your `score.xml` file is not a valid MusicXML file: It contains stuff
like
```
<duration>4/4</duration>
```
but the `<duration>` element only accepts decimal values (and integers
are preferred according to the MusicXML specification).
It actually looks like this file is what MuseScore uses internally for
storing its data (it starts with a `<museScore>` tag). This doesn't
work with `musicxml2ly`; you have to explicitly *export* to MusicXML.
Maybe you've attached the wrong file to the bug report?
After some faffing around, I managed to get Musescore4 installed. It
appears that Musescore4 will not correctly read the output of its own
conversion: it complains about invalid data.
In view of that, the import to Lilypond, although it works, for some
value of "works", is not terribly useful. Thank you for your suggestions.
Further research is required.
