Generative expand with firefly stopped working, screen goes black.

To whomever it may concern,

At first when I would take an image from LRC to PS and use Generative Expand, I received excellent results.  After improving 5 images, now when I use the crop tool to expand and click "Generate" I get a black screen, no more image, and the program shows it's trying to work.  On the Layers Panel it appears to be working but the images there are blurred out.  Mac Studio, Tahoe 26.2

I have 70/100 credits.

Please advise.  Thank you, Kathy Scutt
