I'm on a fresh install of Pop_OS 22.04 LTS, I initially installed Steam as a flatpak, but after not being able to run the game via proton, even with the launch args recommended by others, I wasn't able to get it to launch.

I uninstalled Steam, and reinstalled it as a .deb via the Pop shop app, and was able to get the game to install and compile the Vulkan shaders, but the game just doesn't launch. I've tried again using "gamemoderun %command%" as an argument, I've changed to different proton versions from v9 through to 5.3-16 but I wasn't able to get it to launch.

Not sure what's causing it, maybe it's because I'm using the same secondary drive that I initially played it on using windows as I've added that as a steam library location? Could be my particular setup, but I've had no luck getting it to run, disappointing
