FFXIV won't detect controller inputs on PC most of the time. Part 2.

There's an option somewhere that has your gamepad work when the game isn't the active window. I think it's in System Config > Gamepad.

Windows 10 update loves taking over as the active window without giving any indication.

I can try that, but I alt tab and leave the game open a lot so I'm worried i might bump something and go off flying while im not looking at the game.
Anyway, I also have the setting turned on to reduce the game's framerate when its not the active window (and it does so to a considerable degree, like down to 15 FPS) but my framerate isn't dropped like that when testing the controller, so I'm not so sure this is the issue anyway.
