Plutonium

I’m having the same issue and I can’t seem to figure out a solution. I’m not sure if you’re playing on steam deck but I’m trying to do so and I get the same error. I was told that the steam deck was banned from plutonium usage but I’m not completely sure if that’s true. If you’re not on steam deck, I wonder what the solution for you is and if it will apply to me. Good luck brother.
