MX Simulator

Just started happening today: Plugged my controller in, the light turned on, used it for gta (it definently works just fine), go to sim, still lit up and still definently on - doesn't work at all. Can't play with it, i went to the controls tab and tried pressing a button to replace my throttle and none of the buttons work, and this is only for sim and only just started. Help?

Go to steam controller settings and turn off controller support for whatever controller you're using
