As soon as I open this file, musescore 3 crashes before displaying anything or giving any message. I wonder if there is a triplet in bar 68 that became strange, whereby the file can't be loaded. I remember this from my last session.

Something about a tie going nowhere?

Maybe, via some hack I prevented the crash, now it reports corruption:

Measure 64, Staff 2 incomplete. Expected: 4/4; Found: 9/8
Measure 65, Staff 2 incomplete. Expected: 4/4; Found: 9/8

Fixing that and the score loads again in 3.0
Check those 2 measures, whether my rewrite is what you really wanted, before the fix they looked like
measure64.png
and
measure65.png
clearly an 8th note too much in each

Priority ⇒ P0 - Critical

Most of these messages relate to staff 2. Those for track 4 do too (track 0-3 being staff 1's voices), and it does seem to relate to tuplets.

Here's the hack I used to prevent the crash:

Measure* System::lastMeasure() const
      {
      if (!this) return 0; // added this line
      auto i = std::find_if(ml.rbegin(), ml.rend(), [](MeasureBase* mb){return mb->isMeasure();});
      return i != ml.rend() ? toMeasure(*i) : 0;
      }

I'd rather not see that hack in production ;-)

Possible. If that corruption can cause a crash even in a version that has the corruption fixed, i.e. if the fix only prevents the corruption to happen, but not the crash it gets on reading sich a corrupt score

Status active ⇒ fixed

There is no crash in MuseScore 3.0.2. The score is corrupted in measures 64, 65, but ignoring the warning opens the score successfully.

Measure 64, staff 2 incomplete. Expected: 4/4; Found: 9/8
Measure 65, staff 2 incomplete. Expected: 4/4; Found: 9/8
