1) Open the attached musicxml file created with Capella-Scan Version 9
2) Musescore crashes

I opened musicxml files created by Capella Scan previously sucessfully. Anyway Musescore should not just crash when opening a file.

Severity S1 - Blocker ⇒ S2 - Critical
Workaround No ⇒ Yes

The artifacts from PR #9000 open it without crashing (so one of the numerours fixes in it seems to fix that), but report corruptions:

Measure 75, staff 5 incomplete. Expected: 9/8; Found: 0/1

Use the mscz file I attached or the artifacts from PR #9000 to load without crash. And then fix the corruptions.
That crash is critical, but certainly not blocking you from using MuseScore entirely

Fix version ⇒ 4.0.0

MuseScore 4 doesn't crash on it either , so this issue is fixed

It also reports corruptions, but these are like caused the by exporing software rather the importing one.

Seems it is Capella's Cap2Music.py

Not sure, might be worth a separate issue, reg. the corruption when importing such a file

OTOH MuseScore's PDF import, using Audiveris, pretty frequently has the same issue

I'm not at my computer right now but what version of Musescore could open the file? As far as I know I have latest 3.6 and it bombs out straight after trying to open the file, no warning at all. Now I have not tried version 4 but thats just an alpha so I would not use it for production work. I am actually producing parts from a score for rehearsals and I still have several other movements to do and I don't want to run into the same problem again.

As said: the Articfacts from PR #9000 (basically a development build, needs a GitHub account) and the MuseScore 4 Beta 2 and later nighly builds.
The former produced what I attached above, so just take that and fix the corruptions MuseScore 3.6.2 reports on it.

Thanks. I am not getting into a development build but I'll try 4 beta if the problem occurs again. Thank you very much again for your help. Really appreciated.

The MuseScore 4 Beta has the disadvantage that the mscz files it creates can't be read with MuseScore 3 anymore.
But you'd need neither, just take the mscz I attached further up, it does work with MuseScore 3 (and 4, if need be)
