I'm playing nfs shift on pc. I use an Nvidia shield tv to gameatream. The controller was working perfectly until recently. I can navigate menus just fine everything works as it should right up until I get into a race where everything just stops working. I get no response from any button presses. Anyone have any insight on this? I've tried changing controller presets restarting the game. Rebooting pc and shield tv. I understand that the shield tv is a little niche but as I said everything was working as it should. This has happened out of nowhere.

It may be worthwhile checking for any software updates for the Shield.
It is also possible a recent update is causing your issue.
