Just upgraded to 2.2.2. Not sure but I think it I already had it but I chose to upgrade anyway. Took several minutes to download and upgrade. Now it won’t work. No error messages. When I drag and drop is displays the screen with original on the bottom of the screen then boom! no more topaz sharpen. Not sure where to look for any error messages.
resolved by delete of app, followed by reboot of mac, followed by new install.
