Microsoft just pushed out a second out-of-band patch for their broken January patches. KB5078127 should be available for download in Windows Update.Would this issue have the potential to cause a black monitor screen on boot? Since updating to 26.1.1 I don't always get to Windows 11 login page, before I had no issues. DDU before install of 26.1.1 too.
Edit: Turns out it's a known issue with a Windows security update. Amazing. Just coincided with my AMD driver update.
