My WASD and arrow keys are swapped, and I cannot access my inventory through ESC /u/Lustful_404 Monster Hunter: World

Its pretty much the title really, I have no idea how it happened, just finished up an R-Brachy fight and got back to the lobby only to find out that I cannot move unless I use my arrow keys, does anyone have a fix for this because it is a damn nightmare
