I’m a long time user, less frequent these days, but just now taking the time to learn how to use Sharpen AI (2.2.2). Every attempt to process an image ended with the app crashing when the progress bar reached 100%. I learned about issues with GPU settings etc. and tried several suggestions with no success. I think now I have found what may be a factor. I was moving images into Sharpen AI with the “Open With” command, mostly in ACDSee, but also Nikon View NXi. (Have not tried others yet). When I dragged the image files into Sharpen AI straight from the Finder window, they were processed successfully.
