I'm on a MacBook pro / OS Montery. I've just found that the Artrage file that I have been working on for about a week, when converted to photoshop, will not open in photoshop because it says "This file is not compatable with this version of photoshop". I tried to open in both PS 2022 and 2020 but no go.

I have been easily exporting and going back and forth from Artrage to PS for years. This is brand new. Any ideas would be most helpful.
