Can you go check your Windows Settings > Windows update, and see if you might have KB5085516 available to install?

KB5085516 was released on March 21st to address Microsoft account sign in issue among some apps caused by KB5079473 https://support.microsoft.com/topic/march-21-2026-kb5085516-os-builds-26200-8039-and-26100-8039-out-of-band-09e85404-1cb6-4ed4-9ca5-3e40d74307b9
