DPI button not being recognized as a keystroke

So I've always used my DPI button as melee since i moved to pc in 2021. I remap in GHUB to the "\" key. I've never had an issue until today's update. I thought it may be GHUB, so i uninstalled and reinstalled. That didn't work. I tested it in other games and it works fine. So, it is definitely on Apex's end. It's not game breaking but it is absolutely infuriating when i try to punch someone and turn into a tornado.
