The reason I asked is because the launcher is not the same thing as the server. Rather, the launcher helps you start the server without having to do a bunch of stuff by hand:
But you can still run a Conan Exiles server without using the launcher.
Which brings me to my follow-up question: does anyone know if you can run the Conan Exiles server on Proton? I know BattlEye won’t work, but if you’re running a private server, you don’t need BattlEye.
