HOTAS/Joystick, mouse/keyboard detected, rudder pedals do not show up as a valid controller.

I can only run one mission per game launch. I complete one, once I open another to briefing window the game crashes to desktop. Only workaround is to restart game, make sure there are no lingering processes running before restarting (ps -aef | grep -i steam).

As noted in previous posts make sure bleeding edge beta version of proton experimental is enabled or game will crash to desktop on launch.
