I was using the web version and updated Classic to 11.01 last night. I still had an issue but what I found is that Sharpening has to be set to 0 or to a very low setting.
It didn't take much sharpening at all to crash the image. There was always a ratio to hit with my previous bodies and it was not completely 0 to something else.

Another problem is that the adjustments are not accurate to what I am actually getting when I export to a JPEG.
I need to do some more research.
