Hi,
There is an issue with a certificate at the moment, an update is due to be released on Tuesday 9th November. Please see this document for information: https://blogs.windows.com/windows-insider/2021/11/04/releasing-windows-11-kb5008295-to-beta-and-release-preview-channels/
You could temporarily put your device into the Windows Insider program to get the update / fix now.
Thanks,
Jamie Sabbatella
