CoD MW keeps going back to as if it's new

I am losing my sanity over this game… EVERY TIME I OPEN IT UP the settings are reset. The game starts with the opening cutscene (Unskipable) and then goes to ToS, asking me to agree / decline, then all of my settings (keybinds aswell) are reset to default. I tried to re-install the game, but that did nothing. I AM SUPER DESPERATE over finding a solution, nothing online seems to cut it, tried to delete a couple of folders in there and scan&repair, still, it is the same. HELP ME omfg…
