Any help with this? Installed with OPs scripts, FA works fine through Steam, the client crashes when logging in though. This is on Arch.

Update:
I fixed it, what I did was change config in lutris to windows and back to linux to reset to defaults, changed the executable like it used to be, added INSTALL4J_JAVA_HOME=.. and PROTON_NO_ESYNC=1, changed in Game.prefs my primary adapter to 2560,1440,120 and it works now in fullscreen borderless window.
