Admittedly very new to APP. But it appears the Project Manager's not functioning properly. When I try to either collect or consolidate clips from a sequence (a sequence I have very carefully stripped of all effects and graphics and other weirdness) I get an error ONLY when I choose "exclude unused media". I'm trying to basically move a sequence for someone else to do work elsewhere and ... I just...can't (‽‽). Although I'm really enjoying jumping from Avid Media Compose rot Premiere this is one thing that is definitely making me reconsider. It's critical to our workflow and the Mangement of our projects that these particular functions be stable, reliable and fast. Right now it is none of the things.

Full disclosure: I'm on the new 2019 MacPro.
