Musescore 4 crashes when changing actual measure duration

• May 15, 2025 - 13:35

I realize this has been reported in the past, but I did not see any reports for MuseScore 4. I created a pickup measure and changed the measures actual duration, and that worked fine. But when I try to change the actual time duration for the last measure in the song to match the pickup MuseScore crashes. I tried at least 1/2 dozen times all with the same result. To test I verified it does not occur if I change the actual duration for any other measure; only the last one.

To duplicate:
Open a completed score in 3/4 time.
Select first measure, measure properties, set actual duration to 1/4, close dialog. Select the last measure, measure properties, set actual duration to 2/4. Click apply or close, MuseScore crashes.

Test notes: This did not occur with a brand new, empty score, only with a completed one. I tried deleting the notes from the last measure and it still occurred. I do not have any finished pieces with a different time signature to test.

System: MuseScore 4, Windows 11.

So please attach this "completed score" for further investigation.

I'm sorry, I don't believe I can attach the piece. It's a copyrighted piece of sheet music I purchased about ten years ago that I copied into MuseScore in order to transpose it to my instrument's key signature. My original duplication was with MuseScore 1.0, which may or may not be relevant, as I only recently opened it in MuseScore 4 and allowed the app to convert it. I will try to create a score that is similar (same time signature, has notes, etc.), though if the crash is due to it being a converted score then the crash likely will not occur. Sadly, I'm not a composer, so any other pieces I have from previous versions will also be "duplicated for personal pleasure."
