Reported version
S2 - Critical

Crash while notating

1: Input two notes
2: undo once, removing the second note
3: Ctrl+Up, to octave up first note
4: crash

crashes regardless of ctrl or not, also crashes with undo+down


I am not able to reproduce this in 4.0.0 (on a single flute staff), and I've tried every combination of notes, undoes and octaves up/down.
Edit: This test was performed on Windows 10.

In reply to by Trainzack

tried single staff with same issue, however i tested two other computers and indeed wasn't able to reproduce there.
Machine with issue:
- Win11_22000.1219, mid-range laptop
Machines w/out issue:
- Win10_build_19045, high end desktop
- Win10_build_19042, low-end laptop

Doesnt seem performance related
Possibly OS related but not conclusive

I have independently encountered this bug on a Windows 10 laptop, and can consistently reproduce it on both stable 4.0 and in the latest (002fd32) nightly. I create a new score using the ”General->Treble Clef” template, enter two quarter notes, undo once, half-step or octave up or down, observe the crash.

I'm consistently getting this on the latest release (updated yesterday). I've only tested with the voice instrument, but can confirm that it also happens in a blank file. To reproduce simply enter two notes, then hit ctrl+Z followed by ctrl+up.

Below is copied from the about window in MS, but I'm actually on Windows 11. This would confirm what toidinami mentioned about this crash possibly being related to OS version.
