BRING BACK PS 21

I'm a simple game modder. I create these for myself to improve gameplay, create new assets, and change textures. Unfortunately, due to the lack of Photoshop version 21, I can't change textures (as effectively and easily as I'd like). I'm interested in the 3D capabilities. In versions prior to 22, there was the option to create a UV mesh, which made work much easier. Now, although this option is available, it doesn't work, and the editing itself is severely limited. I know it worked because I used it myself, but I decided to downgrade, thinking it would be better. Now I can't install the old version and I'm at a loss. Please allow us to download version 22 so I can easily pursue my passion.
