Hi I've been encountering this problem for sometime.
When exporting projects with several layers, Quill freezes and crashes. I've tried exporting layers individually with the same result. The problem seems to occur more often when I imported an image (in this case 360 image) into the project. The crash occurs even after deleting/hiding the image.
Possibly related (although the issue existed before), the Quill app is "taking longer than expected" and I receive the attached error message. I've tried reinstalling Quill, and then reinstalling the Oculus app with the same problem.
Thanks for any help!
