Voice 2 on guitar tablature results in corruption

[YoavShilon05]

Issue type

File corruption

Bug description

When trying to convert a Voice 1 note to a Voice 2 note on any tablature instrument (electric guitar, bass, etc...) the score corrupts.
This occurs only on a specific file and only when editing the part directly (not when editing the main score), I wasn't able to reproduce it from scratch.
I should also mention the file was created on version 4.1 of Musescore.

Steps to reproduce

1. Open the attached file "Starless.mscz"
2. Open the part of any tablature instrument (Electric guitar, for example)
3. select any note and convert it to Voice 2
4. The tablature should appear empty where the note once stood.
5. Sometimes the score doesn't recognize it's corruptness immediately. any tweak to the broken note should evoke corruption (like adding a tie, changing it's duration, etc...)

Corruption confirmed on MacOS Ventura 13.5.2

When following your instruction on the B notes in M11:

    • The corruption Alert appeared on SaveAs
    • Undo did not remedy

Prior to testing I opened and immediately saved your Starless score without issue—no corruption was announced. I suppose that suggests corruption did not exist within the attached score, unless something is flying below the radar.

I tried the instructions on other several other notes and didn't provoke corruption.

But also found there were Voice 1 notes that would not move to Voice 2. For instance the triplets in M17 and M19. So that's peculiar.
