Also want to confirm that the preview area in Pixillion does not show the heic file. Preview shows white/grey checkerboard. Dimmensions look reasonable (4032x3024) but color depth is 0bpp.

I have the same issue. heic to jpg for 10 files gives me 10 identically-sized jpgs (187KB), all of them black. Original heic files range in siae from 1 to 2MB. I have put in request for tech support, but seems like a forum discussion is more appropriate when multiple users are hitting the same problem.
