So I am trying to mod fallout new vegas to do another playthrough on it and I am following Viva New Vegas as the modding guide. The problem is that when I try and run the install.sh file on my pc it keeps saying it cannot find the prefix for Fallout New Vegas. I have already enabled Proton 9.0-4 compatibility on steam, and I have even regenerated the prefix (i think I did so correctly, used ChatGPT for that lol) but it still does not work. Ostree is not compatible with Protontricks so I had to create a toolbox to run protontricks inside of, but I still cannot figure out why it will not register the installation of New Vegas even though so many others it works perfectly fine for.
