Musescore 3.2.3 crashes when opening a file with Staff Type Change setting.

• Jul 16, 2019 - 19:46

I am working on creating a children's music program using colored notes and pitch names with the Staff Type Change in the text dropdown. I have made a copy of each file using the colored notes, and black notes with the Staff Type Change and they both crash when opening. The file that does not have the Staff Type Change does not crash.

Here is my system number, software version, and reversion:

OS: macOS High Sierra (10.13), Arch.: x86_64, MuseScore version (64-bit):, revision: d2d863f

In the files, the CD TRaxNC is the black notes, the CD TRax copy is the colored notes.
