Windows 10: Turning HDR off causes my pc to restart and keeps HDR on.

I've been having this issue for the past couple of days. I noticed my screen had a yellow tinge to it. I know for a fact I never changed it to that. Nobody else goes on my computer let alone know how to change the settings. My monitor that is being used is the Acer Predator XB273U GX @ 1440p 270Hz. My gpu is the EVGA FTW3 ULTRA RTX 3080. Not sure if this is a windows update issue or an nvidia driver issue. I tried using DDU and clean installing the driver but that didn't fix the issue. Not sure if I really want to reinstall windows because this computer is practically brand new Built in March

HDR on HDR monitor causes issue on secondary, non-HDR monitor

I have an Aorus AD27QD (HDR) monitor as my primary display and an ultrawide 34UM88-P (Non-HDR) as my secondary. If HDR is enabled in windows and I go to a full screen video on the non-HDR monitor after a few seconds it will flicker blue then become severely
washed out. Coming out of full screen fixes this. If HDR is not enabled full screen shows the colors perfectly normally.

Secondarily, with windows HDR on on the Aorus, the colors dim pretty drastically. HDR content great but anything that isnt HDR is dim enough to make me question if my brightness is turned down. (Its not, its 90/100). The white of a plain browser window
seems so dim its nearly grey. I also tested this on what I know is a particularly vibrant (non-HDR) . HDR on? Terrible and muted. HDR off? Bright and vibrant.

I have played with in-monitor settings, nvidia control panel, factory reset of monitor, basically everything I can think of. Everything points to it being a windows issue.

I also tried out the suggestions from this post. And it pointed me to this
set of OS release notes which didnt solve my issue either.

I could really use some help because I am really feeling like I wasted my money on this monitor.
