Issue with Xbox One controller for PC version of both Tekken 7 and Tekken 8 Demo

When using my Xbox One controller for Tekken 7 or the Tekken 8 demo on my PC, whenever I hit an opponent or they block an attack, the game's pause menu opens. This happens on each hit and not on input, so if I do a can-can, the game will pause when the first kick lands, and when I close the pause menu, it will pause again as the second kick lands. Similarly, the game will pause on each hit if I do a throw like Steve's ten count.

I've tried different usb ports on two different PCs and both have the same problem. I also tried changing various Steam settings related to controllers and inputs and they didn't fix this problem.

I don't have any issues using this controller for other games.

I don't have this issue when using a cheap generic gamepad I have, and also didn't have this problem when I used a DS4 (which I no longer have) when playing Tekken 7.

Does anyone know if there's a fix for this problem for this controller? And how does something like this even happen?

Thanks for any responses.
