Crashes immediately, but file opens fine the second time. Only difference is that Photo AI was already open from a prior edit, though that edit had already been closed. Photo AI invoked directly, not via Photoshop or some such.
Also if you can, please try to recreate this crash in Topaz Photo AI, then go to Help > Open Log Folder, please send me all of the files within that folder. You should be able to attach them directly as a response to this thread.
