I can't do a Left Ground Grab during the mission Transition 101

If you're using Steam Input, it sometimes rebinds the triggers to be the bumpers, and just unbinds the triggers entirely. Try checking your controller bindings!

Hi! Do you by any chance have a keyboard with magnetic or hall effect switches, like a Razer or Keychron? If you do, try unplugging it to see if that helps. Also applies to any non-standard peripheral like a flight stick or racing wheel.
