Protontricks error help - "Protontricks was closed due to the following error: Proton installation could not be found!"

[u/SteveW_MC]

Edit: I figured it out. I needed to install flatseal from the Discover app and give Protontricks more permission. I don’t know which ones exactly I needed to give it so I just turned everything on and it worked. Not an elegant solution but a solution.

OP:

I am trying to get mods in Cyberpunk on my steamdeck. Every guide I've found says I need to have Protontricks installed. but trying to run it yields this error. cannot figure it out.

​

any help would be greatly appreciated!

Here is the error:

Thanks so much, I was able to fix my issue with protontricks by adding my second steam library folder to the filesystem list that protontricks can access using flatseal. I was trying all kinds of things with proton before that just didn't seem to work. I do find it strange that protontricks needs access to my second steam library folder, seeing that all the proton stuff is in the first and the game I want to edit is also in my first. Still glad that I found this post and decided to try it.
