Proton 4.11-5 starts up, but the first window throws up two warnings. 1: "Mono runtime detected, dotnet clr" recommended" 2: "Detected Wow64 mode: False" Next window hangs on "Running elevated setup to associate file extensions and setup firewall rules" If you close the blank terminal window it will continue, but eventually gives you a error window with this: System.Exception: Staxel.Client.exe process closed quickly with error code: 0x00 at Plukit.Base.FormExtensions+NativeMethods.StartProcess (System.String path, System.String args) [0x000bd] in :0 at Plukit.Base.FormExtensions.StartProcess (System.String path, System.String args) [0x00000] in :0 at Staxel.SteamLauncher.SteamLauncherForm.RunGame () [0x000a3] in <713aba7031db4d0bbbdff41ed7ce2bb5>:0
