Dorico crashes after opening Noteperformer's midi settings

Hello everyone, this is a new one. Macbook OSX Sequoia, Dorico 5 and both with Noteperformer 5.0.1 and latest (5.1.2). Whenever I open Noteperformer’s mixer up and going back from playback view to any other view, Dorico freezes. Project is 14 bars of 6 voices completely empty. Already reinstalled Dorico as well. Never had such issues before. What can I do? Thank you very much!

Could you please choose in Dorico from the menu Help > Create Diagnostic Report and post the corresponding zip file in a reply here? Hopefully it contains freeze dump files which tell us where Dorico is hanging.
Thanks
