Re: PS5 Controller support on PC

I had the same problem but with a PS4 controller. After many hours i found a way that worked for me. Plug in your controller and go to steam controller settings > check the boxes next to guide button focuses steam, ps4 configuration support and xbox configuration support > add NFS Unbound as non-steam game, add NFS Unbound Trial as a non-steam game and also add EA Desktop app to steam > launch ea app from steam > after ea app starts running launch NFS unbound and leave the ea app and steam running in the background. 
Very unusual and unnecessary but i hope this helps.

PS: always plug in your controller before you launch any other program and also the ea app must be fully closed before you start playing again after you close the game.
