OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 3.2.2.7534, revision: c893c61

1) New score for flute, two voices (1 & 2)
2) Enter a few notes in each voice, and with at least two time signatures in the score say 2/4 and 3/4
Test file at this step: Flute.mscz
3) Create individual parts for Flute1 (Voice1) and Flute 2 (Voice2) -> Ok
Test file at this step: Flute parts.mscz
4) Toggle in Parts

Result:
In first part, as expected

In second part, unexpected. The 3/4 time signature change is lost. Hence corruption, leading to crash.

  • Same result if other voices 3 & 4. Only the voice1 honors the time signature changes

There are a couple of other serious issues with this feature, I'm guessing they are somewhat related and might not be that hard to fix. Would be nice to get this working for real, although it will still be limited in that it's "all or nothing" - no way to have passages written in only one voice get shared.

Well, from the moment a score is corrupted, the crash is really underlying, and a nothing (or a little more depending on the score) can cause it. E.g. on this score ( fanfare2 parts.mscz) , go to measure 36 -> input double whole note (type 8), and repeat ("R" key) say 3 or 4 times. The crash will occur.
