Screen Turns White or Intense Lights / Colors

I am experiencing the EXACT same issue. It only happens in GA. I can go back to the Main Menu, Arcade Mode, Options, Scoreboard, HvV without a white screen. I have to restart the game to play in any GA matches after it happens. It occurs out of no where with a warning sign that its about to happen when the frames slow and then I know its only a matter of moments before I get the big white screen of death again. Started with the introduction of the Squad System Patch.

Here is my DXDiag.  Thank you for the attention.  Sorry I haven't been able to respond quickly.  I've been travelling and working a lot.  I also wanted to see if Windows / driver updates resolved the problem, but no joy.

Also, while this is a separate issue, can anyone point me to possible solutions for drop in performance related to Windows updates?  Ever since I moved past 1709 my FPS have suffered.  I used to revert back, but last time I tried that I got stuck in an infinite reboot loop.  Somehow I recovered, but then the next day I had an issue saying my PC needed to be repaired.  Several phone calls later I had a fresh install of Windows 1803 with no option to revert.  October update hasn't helped much.
