Currently with the latest version of Vorpx (18.2.3 at the time of writing), no matter what game I try to launch, if I have my Xbox One controller plugged in, as soon as I touch a button on the controller or move an analog stick, the game instantly freezes and crashes in Vorpx.
Dunno if this is a known bug, I noticed Ralf saying in another thread that there was a problem opening the menu, but I don’t have to do that to get the crash, just press any button at all on any game.
