Hi,
Thank you for the update on the issue.
As the scan completes but could not performed the requested operation so it means there is some corruption with the system files. Before performing Refresh, there are more steps which we can try, as Refresh used to be the last step of troubleshooting.
Try to perform clean boot and disable security software temporarily and then try to install updates. There might be a chance that security software is restricting it to get installed or some third party application/services/startup items are restricting it to get installed.
Step 1: Clean boot
Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

**Note:**Refer "How to reset the computer to start normally after clean boot troubleshooting" to reset the computer to start as normal after troubleshooting.
Step 2: Disable anti-virus temporarily.
Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.
Step 3:
Try to install the updates and check the status of the issue.
