Score needed. At least the mscz and probably also the mxl. Then again it might well be a Sibelius issue

Thank you for your swift response maybe u can teach me what may have happened here so that I may be able to resolve it on my own in the future?
That mxl file is invalid:
Fatal error: line 52462 column 10 Unexpected ' '.
loading it (in MuseScore) regardless claims it to be corrupt:

So indeed MuseScore musicxml export seems to be at fault here

Seems to fix that.
Does Sibeliuss like this better?
In reply to Changing <stem>up<… by Jojo-Schmitz
I sort of found out the cause of it! Apparently it's this bracket in bar 65
Using the current master (ec75e63 of Apr 20):
the attached .mxl file
- is correctly diagnosed as invalid due to the "stem" issue reported by Jojo (which is present in the file only once)
- does not load (it aborts due to a failed assertion "_e.isEndElement() && _e.name() == "note"" at importmxmlpass1.cpp line 2618)
Indeed the bracket in measure 65 was causing the incorrect export. The current master does not suffer from this issue anymore, the bracket is exported to and imported from MusicMXL correctly. Setting the status to fixed, even though I haven't identified the commit that fixed it.
Note that there is no "stem" issue, apparently an error in the MusicXML exporter generated incorrect XML for a middle note in a bracketed chord: an unnamed element containing only attributes.
Also note that this "unnamed element" issue causes the abort, as it leads to the MusicXML importer getting out of sync with respect to the XML tokens in the input stream. In theory this could be fixed, but a complete solution would require changing all MusicXML parsing routines dealing with tokens. For an issue that occurs only with a kind of invalid MusicXML that is unlikely to be encountered again, I doubt making a fix is worthwhile.
