You do not have permission to open the application “Adobe Photoshop (Beta)”.

Most likely you need be 18 or older —and then tell Generative Fill that you indeed are 18 or older. You need to have a valid date of birth associated with your Adobe ID. Here is the pertinent part; the weblink follows.

Please let us know if this helps, as Generative Fill is new to all of us.

Perhaps signing out and in to Creative Cloud might help.

You might try uninstalling it using Adobe Creative Cloud, then reinstalling it again.
