Just finished chatting with a SE support member via their live chat. They resolved that I've already done all troubleshooting steps they'd recommend and that they could not help me. They instead pointed me to seek help from Microsoft or Nvidia for support. They also suggested I submit a formal bug report.

I'm understandably deflated as this problem only started occurring when this patch was pushed. I can't think of any other change to my system that would have created this problem for me that coincides with what others are experiencing...
