Nuendo 11 Score Editor Bug

I just upgraded to Nuendo 11, and the Score Editor window immediately closes whenever I input a note. I’m working on an i9 ASUS ZenBook Pro. It’s frustrating, as I’m eager to explore the new functions for my workflow. Any advice?

I’ve opened an empty instance of Nuendo 11, and the Score Editor works fine without crashing. However, with increased track counts, it crashes.
