Hello James,

I realize that the updates are not installing in Windows updates. We will help you.

This issue might have caused due to some third party security apps or third party apps conflicts in Windows.

Let's try the below steps and check if it helps to resolve the issue.

Method 1: Place the PC in clean boot state and check if the issue resolves.

to disable all non-Microsoft services consult the article called Clean Boot.

Note: A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows. You may also troubleshoot or determine what conflict is causing the problem by performing a clean boot.

Disclaimer: After troubleshooting, refer to this section "How to reset the computer to start normally after clean boot troubleshooting"

Method 2: I suggest you to run an inbuilt Windows update troubleshooter which helps you.
