To reproduce:
1. Open the attached file Crash_Boom_Bang.mscw
2. Switch to voice two (I used Cmd+Opt+2 for that).

The document has been created with two staffs, Soprano and Alto, and a Part has been added that includes Soprano voice 1 and Alto voice 2. The Soprano and Alto voices have been Imploded. This is an odd combination of things, but one that I managed to accidentally create (and then experimentally tried to recreate for a while after).

Also attached is the backtrace generated for this file on my Mac running macOS 10.14.6

I can't reproduce. What note(s) exactly should get switched to voice 2, and in score or in part?

Title Crash when switching voices in document using parts with single voice selection ⇒ Crash when switching voices if notes are tied
Workaround No ⇒ Yes

Workaround is to delete the tie prior to the voice change.
Not related to parts pr single voice parts at all
