The recent Windows 11 update has resulted in login issues with certain apps, including Teams, OneDrive, Microsoft 365 Copilot, and the Microsoft Store. Microsoft has confirmed that these issues are due to an update KB5079473 for 24H2 and 25H2. The issue appears to be caused by a lack of internet connection, but Microsoft is investigating the issue and plans to release a patch in the coming days. If you're using Windows 11 Home, you are missing out on the many benefits of Windows 11 Pro.
