Musescore Crashes when deleting an instrument
Please find attached a score with two instruments... Electric Guitar and Accoustic Guitar.
When attempting to delete the Electric Guitar musescore crashes, without deleting the instrument.
Some possible insights:
* The score started out as ELECTRIC guitar only, with a linked TAB.
* I attempted to drop the ELECTRIC guitar and linked tab, but it crashed.
* I was able to drop the TAB with no issues, but still unable to drop the ELECTRIC guitar
* After moving the ACOUSTIC guitar to be the #1 instrument attempts to drop the ELECTRIC guitar still crashes musescore.
I assume the attached diagnostics file contains all of the system/environment info needed.
Thanks,

I cannot reproduce the crash. No problem here, I can remove the Electric guitar (version 4.4.4, Windows10)
In the Instruments panel, I select the Electric Guitar, then click on the recycle bin, and get a score with the Acoustic Guitar alone.

The OP apparently is using a Mac, where MuseScore might well crash under different circumstances than on Windows
Interesting. On my system, removing the acoustic guitar causes the crash. No matter what method I use.

" removing the acoustic guitar causes the crash"
Me too.

Are you sure you're talking about deleting the Electric Guitar (the 2nd instrument on your score), or are you mixing up the 2 instruments in your message?

I can confirm that.

In the latest builds it crashes on deleting the Electric Guitar and undoing that

I can reproduce from scratch (1 or 2 measures are enough)
Selecting and removing the first instrument leads to a crash. Removing two chord symbols (C) or fretboard diagrams (which, in effect, also remove the chord symbols) solves the problem: test chords.mscz

The rule is simple - crash when deleting any top staff if the last staff contains a freatboard

That's it. And of course it deserves a report on Github.

In which previous version did this work? Not in 4.4.4 for sure.
Nor in 4.3.2 or 4.2.1, Cant't test (with that score) with earlier versions.
Actually I can, with a file created from scratch, reproduce with 4.0.1, but not with 3.6.2

See https://github.com/musescore/MuseScore/pull/26524 for a possible fix (which does feel like band aid)
