Hi Matthew,

Open the Settings App.

Go to Windows Update - Update History.

What is the KB number of the update that is causing the problem, is it the optional preview KB5095093 update released at the end of June.

Just checking in with you, have you checked which Windows 11 Update is causing the problem.

Thank you for that information.

That is the monthly June update, that is most likely updating the Secure Boot Certificates on your PC because some Secure Boot certificates in BIOS expired in June, the best option is to pause your Windows 11 updates until the July update is released next Tuesday, and in the meantime, ensure you have a safe backup of your files to ensure against data loss.
