Microsoft said in an update: ‘Starting on November 1, 2021, some users might be unable to open or use certain built-in Windows apps or parts of some built-in apps that have not installed KB5006746, released October 21, 2021. This is caused by an issue with a Microsoft digital certificate, which expired on October 31, 2021. Devices running in S mode are more likely to be affected.”
