NGS PC - Xbox One controller not recognized. Xbox 360 controller works fine

Wondering if anyone else has run into this issue. PSO2 NGS simply refuses to recognize my Xbox One controller. I tried it both wirelessly connected via the official USB dongle and wired. Still doesn't work. After trying a bunch of weird stuff--including disabling a bunch of Razer product devices that were additionally reading as controllers for some reason--I decided to try an old wired 360 controller I had lying around. Worked instantly with no trouble.

My Xbox One controller works perfectly well with every other game. Has anyone else encountered this? Is this a known issue?

My Xbox one controller will also not work using the Windows Client. Funny enough, Steam finds and works with it on New Genesis with no issues.
