possible bug in the version 2.2.20

I have two projects and I want to import the flows from one of the projects into the other. But no matter how I do, Dorico shuts down without warning.
I can send the two projects to you attached to an e-mail if you want to investigate.

You can send the projects to me by email at d dot spreadbury at steinberg dot de. Be sure to specify which flows from which project you are trying to import into which other project.
