I'm using a X-Box One controller on Windows 10, totally updated and properly working, but this game (and only this game) gives me an error saying the controller is not connected when it it.

This happens wirelessly aqnd wired, when starting the game plugged in and pluggin it in in game, it completely seems to be unable to recognize my gamepad.

Is this a known issue?

I see people complaining that you can't use two gamepads, but I've seen nothing about not even being able to use one of them,

Same with my XBox360 gpad. First game to not seeing it connected.

Ah! Answer is in a 1-star review:
"gamecontroller support is clunky at best.
- game starts in KB mode whether or not gamecontroller is connected
must enable gamecontroller under options,
then exit and controller must be connected before relaunch
- also enable autoaim otherwise very hard to aim as it tries to use the
right-stick for mouse aiming "
