newElement(Element.NOTE) crashes Musescore 3.2.3 on Ubuntu

Hi,
I'm writing a plugin creates a Score with all forms of a PitchClass Seqeunce (Row, etc.).
It works if I create notes using cursor.addNote(pitch), but if I try to create a Note Element, MuseScore crashes.
I've been able to isolate the crash to the statement which creates the Element:
var newNote = newElement(Element.NOTE)
I'm running MuseScore 3.2.3 on Ubuntu. I could also try it on a Mac and post an update.
Here's the functions which generates the score, which otherwise works when calliong addNote(pitch).
Any ideas would be much appreciated.


function generateTTOScore() {
var myScore = newScore("TTOs", "Paul M", 24)
myScore.startCmd()
myScore.addText("title", "TTOs")
var pcMod = 12
var multipliers = [ 1, 11, 7, 5]
//var row = [ 0, 11, 1, 2, 10, 8, 5, 3, 9, 4, 7, 6 ]
var row = getSequenceFromText( pcSeqTextArea.text )
var baseTimeSig = newElement(Element.TIMESIG)
baseTimeSig.timesig = fraction( row.length, 4 )
baseTimeSig.visible = false
var oCursor = myScore.newCursor()
oCursor.rewind(Cursor.SCORE_START)
//oCursor.rewindToTick(0)
oCursor.add(baseTimeSig)
//myScore.appendMeasures(20)
oCursor.setDuration(1, 4)
oCursor.rewind(Cursor.SCORE_START)
//var index = 0
for (var multIndex = 0; multIndex < multipliers.length; multIndex++) {
for (var transIndex = 0; transIndex < pcMod; transIndex++) {
var elText = newElement(Element.STAFF_TEXT);
var transformationString = "T" + transIndex
var multString = ""
if (multIndex == 5 || multIndex == 7) {
multString = "M" + multIndex
}
if (multIndex == 11) {
multString = "I"
}
transformationString = transformationString + multString
elText.text = transformationString
//oCursor.add(elText)
for (var rowIndex = 0; rowIndex < row.length; rowIndex++) {
var pitch = ((row[rowIndex] + transIndex) * multipliers[multIndex]) % pcMod
if ( pitch < 3 ) {
pitch += 12
}
if ( rowIndex == 0) {
elText.placement = Placement.ABOVE;
elText.autoplace = false;
oCursor.add(elText)
}

if ( newNote.accidental == null) {
