Consistent Crash when Deleting Measure

Hello Musescore Community,

I have a project file that is consistently crashing on my system. Here is what I'm using:


OS: Universalblue (use audio applications in an Arch container from distrobox)
Kernel: Linux fedora 6.12.15-200.fc41.x86_64 #1 SMP PREEMPT_DYNAMIC Tue Feb 18 15:24:05 UTC 2025 x86_64 GNU/Linux
Pipewire
Musescore 4.4.4-2 (using from Arch Linux in distrobox but the crash also occurs in the same version flatpak)


Basically, if I try to delete measure 59 in this musescore file in the treble clef, it immediately crashes musescore. This is a problem, since I'm currently on a tight deadline for notating and writing this harp piece. Any help would be appreciated!

I tried rolling back to a previous version of musescore to see if I could continue, but previous versions won't open newer files. I guess I'll just have to export music xml and continue in lilypond.

Here is what the output of the application says when launched from a shell:


/usr/include/c++/14.2.1/bits/stl_vector.h:1237: std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::back() [with _Tp = mu::engraving::MeasureBase*; _Alloc = std::allocator; reference = mu::engraving::MeasureBase*&]: Assertion '!this->empty()' failed.
Aborted (core dumped)
