Try to manually update Windows 11 instead, simply visit the Microsoft Update Catalogue website and download the update you are currently having problems with.

Run the Windows 11 Corruption Fixing Tools
The DISM and SFC tools on Windows 10 and 11 are some of the most versatile tools on the operating system and will help solve just about any weird OS problem you may be having.
