Inserting some frames are crashing Mac Catalina MuseScore 3.6.0
I have attached some files.
I would like to produce a similar page like in the Afro_example.pdf (made with Sibelius).
The closest I can reach is in the file Afrotreeni 3.6.mscz (see also Afrotreeni 3.6.pdf).
Problem is that I can't insert the vertical frame inbetween nor the text frame, because Musescore 3.6.0 crashes immediately. Only text-frame at the end is possible (and dragging it to somewhere).
Crashing is independent of the settings of the page style "Enable vertical justification of staves".
I included the Musescore file for all of you to explore.
System: MuseScore 3.6.0, Mac OS Catalina, MacPro 2013 (12core, 128Gb RAM)
