This would fix your issues if this was the cause. Exit the Group Policy Editor and then reboot your computer for the changes to take effect.

You need to delete the contents of the SoftwareDistribution folder & reset the Catroot2 folder.

Updates that have failed to install will display Failed under the Status column.Next, go to Microsoft Download Center, and search for that update using the KB number.Once you find it, download, and install it manually.
You could use Microsoft Update Catalog, a service from Microsoft that provides a listing of software updates that can be distributed over a corporate network. Using the Microsoft Update Catalog can prove to be a one-stop location for finding Microsoft software updates, drivers, and hotfixes. All the best!
