Generative Füllung (PS Beta) [Branched]

Hi, I have a similar issue with Photoshop Beta and the Generative Fill.

It actually worked fine but the last days I can't make it to work. It is not Greyed out or inactive. It seams to work properly but it is not generating anything. The loading process when I generate something stops very fast (mainly I try it without writing something, I just press the generate button to clear/remove something).

Any help on that?? Thanks in advance!
