Photoshop Generative Fill Beta Can't Install

Hi there
I've just downloaded the CC from the website to try PS Beta with generative fill. In my CC I found the Beta version but when I clicked try beta it pop-up my country doesn't support it to buy. I'm sure my country is supported and even some friends already try it. So, I have no idea what's wrong.

My Device - Zephyrus G14
OS - Window 11
CPU - Ryzen 5 4800H
Graphic - Nvidia GTX 1050 Ti 4GB
Ram - 16 GB

Storage - SSD 512 GB
