DCP Wraptor export stalls and crashes

Over the last few months I've had to export multiple short DCPs through AME with increasingly diminished returns, weirdly enough. All files have been ProRes 422 or 422 HQ 1920x1080, 24fps and all DCPs have been 2k flat, 24fps, JPEG2000, Progressive w square pixels.

Originally it seemed like every export over around 15 minutes would stall out and crash, but in the last month it's worsened to the point of no DCPs finishing encoding. Both Premiere and AME are up to date and I'm on OS X 10.11.6.

Seems like its probably the same issue as this thread from Feb: Wraptor 2K DCP crashes which was marked answered with Adobe promising a fix in the next update. I haven't heard anything since and strangely don't see too many people having this problem across the internet.

Thanks for any ideas/fixes.
