Part 1 (PC) I can not change the key bindings 😭

I want to change the keyboard and mouse mappings in the game, but I can't because the system isn't registering any key presses. I'm playing on an Asus ROG laptop and have already tried several things, but haven't been able to solve the problem. I don't have a controller connected, just the keyboard and mouse. I've disabled controller input in both the game settings and on Steam. I can also access and select the individual key bindings in the game under "Customize Controls," so I should be able to enter a new key binding, but no matter which key binding I try to change or which key I press, nothing is registered. Does anyone have a solution for my problem? I'd really like to play the game, but not with the default key bindings.
