generative filling does not work

[n_nastya]

Installed the free 7-day version last night Adobe Photoshop and Adobe Photoshop(beta) , and I can't use the generative fill. When I try to use this function, the following notification pops up.

"To access Firefly-based features in Adobe applications, you must have genuine Adobe applications installed".

 Although I was downloading everything from the official website.
