I dont think its a bug related just to the joypads. I also have experienced this on 3 different machines of the latest HyperSpin build, the entire interface becomes unresponsive to joypad and keyboard inputs even though the interface is playing video and spinning around themes by itself after a few seconds of inactivity, yet I can Alt+F4 or Alt+Tab out of HS and restart. Also this can happen (rather unfortunately) after a minute of first launching HyperSpin, or randomly kick in at any point but it fortunately occurs quite rarely.
