Colours extremely Oversaturated

This has been a problem in the past and I've usually just uninstalled after hours of troubleshooting and playing something else. I reinstalled recently and everything was fine for a while, until I tried to change the mode from fullscreen to Borderless so that it wouldn't freak out every time I hit alt tab. And alas, I had provoked the benevolent deities that seemingly haunt my pc and this game because the colours just became sickeningly saturated and bleed out everywhere with banding as well. Hours of troubleshooting later and no progress has been made, except that it seems to be fine on my secondary monitor, but its my secondary monitor for a reason so I really need this to be fixed on my primary. Im running through epic games and yes, I have literally done every conceivable combination of hdr toggling in the game, in windows, in nvidia, on my monitor. I attached some screenshots but idk if they will even convey how gross the game looks, the menu ones seem to though. Help me dead Battlefront 2 forums, you're my only hope.
