Roto Brush 2 Crashing Round Trip Workflow

Clip on timeline in PP 14.4, Mac OS Catalina

clip: MXF 4k via Sony SF7, 29.9FPS

1. in PP 14.4. Right click replace clip with AE comp, to start the AE Roto.

2. Save AE 17 project, apply Roto Brush 2, works great, looks good. Freez roto.

--Go to Premiere project, PP shows the Roto update looks good. Advance playhead with click.

--AE shows Roto propagation again, then crashes.

clip lenght 10 seconds talking head limited movement.
