The game is not detecting a controller in gameplay or menus. I tried both the DX12 and DX11 versions and neither work. But if I launch Cyberpunk it detects it or if I launch a game through steam it works fine as well.

I was trying this with an Xbox controller and even tried 2 different controllers and it didn't work. But it does work with a PS5 controller.

I can reproduce that reliably. Did CD Projekt Red not test anything at all? What the...

Only way I get controller to work is to play the game through Steam.
Gog is bad enough already, but forcing you to play through another service just for controllers to works is terrible!
Worst of all, it was working fine before "next gen" update..

...and that's how GOG makes people to go to Steam, since otherwise its own game is evermore broken. Yikes!
