Some VST not working in Adobe Audition

Not sure what's going on but there are VSTs that refuse to work in Adobe Audition using Izotope 9 on an M1 mac.

Have you checked that you are running the latest version of iZotope RX9, which is 9.3.0.1345?  Though not a MAC user, I seem to remember that version was stated to be fully compatible with the latest MACs.
