To be SURE that I'm not "misrepresent basically everyone involved": Right now I tried the Proton build the PR creator made... and Photoshop still does not work. It shows the activation screen with "Loading..." written on it (sometimes it is just a blank box). https://i.imgur.com/QN2rxoO.png

You also aren't able to install Creative Cloud with that fork, the Creative Cloud installer gets stuck on a loading loop, so I needed to copy my Photoshop + Creative Cloud installation from my other Wine prefix.

This is not me throwing the PR's creator to the curb, it is impressive that they were able to fix the installers, even though they aren't the "main" installers, and I'm pretty sure that the PR creator could fix the activation screen too, because I think the issue is similar to the ones they are fixing, they probably just didn't do that yet because they don't know the activation screen is also borked.
