Stuck on a 2017 SSD iMac (i5) with freshly installed 1.0.4. My daughter asked me to enlarge some of her digital artwork.
Tried a simple batch of 2 images, each with the same settings (applied to each manually). Very slow on Intel 
Got this error:
Running that failed image on its own worked. Model was Graphics at 2x.
I don’t usually batch-process but it seems there is some difficulty there for others.
My daughter’s iPad/Procreate-generated image enlarged 4x in Photo AI (Graphics mode) and ready for use as a bedspread, etc.!
Also, Photo AI 1.0.4 used under the new macOS Ventura beta 11 on M1 MBP DOES NOT exhibit the previous graphics glitches using 4x and Natural mode. So that fix is holding.
