Chords not playing back in Play, No VST showing up in Routing dropdown

For some reason, I can not get the Chords track to recognize Note Performer or any other VST so I can’t hear chord playback. Here is a chart… I haven’t had this issue before…any ideas? And for some reason I cant upload a dorico file here; it says it is too big?

You don’t have to load the whole thing to demonstrate the problem.

(Presumably, since you say you have done this before, you have assigned the chord track to a playback sound in Play.)
