MuseScore does upload the score apparently (it is on musescore.com afterwards, but then crashes.

Might need to get reported to the Qt folks

Just reproduced this in VS2019 16.6 using Qt 5.14.2.

Crash:

Exception thrown: read access violation.
content::WebContentsDelegate::GetJavaScriptDialogManager[virtual](...) returned nullptr.

Function where the crash occurs:

void WebContentsDelegateQt::CloseContents(content::WebContents *source)
{
    m_viewClient->close();
    GetJavaScriptDialogManager(source)->CancelDialogs(source, /* whatever?: */false);
}
