In MuseScore 4 (and I guess in MuseScore 3, too) you can select the
the output format while saving the file (i.e., selecting the proper
file name extension). You have to select 'MusicXML'. This output
file should then be readable by `musicxml2ly` (with some hiccups here
and there which I try to slowly improve). Does this work for you?
It is a known fact that there is no round-trip compatibility available
for MusicXML. This means that there will *always* be some loss of
information during export. Note also that, AFAIK, MuseScore is better
at exporting MusicXML than reading it. This is true even with the
most recent versions.
