Hi slancio
I am Vijay, an Independent Advisor. I am here to work with you on this problem.
I recommend that you do a manual update for this KB.
1. Windows Key+X > Windows Powershell (Admin)
Type following (or copy and paste following) one by one and Enter
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
Ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
Ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
2. Type following in Windows Start Search box (Cortana) and hit Enter %systemroot%\Logs\CBS > Rename CBS.Log to something else.
If it doesn't allow you to rename - Type services in Windows Start Search box > Click Services > Scroll down to find the Windows Modules Installer service and double-click on it > Set its startup type to Manual > Reboot your computer
Go to C:\Windows\Logs\CBS > Rename CBS.Log > Reboot your computer > Then go back into the Services App and set Windows Modules Installer Service back to Automatic Startup (Note CBS log files contain information about windows update, SFC etc)

3. You can download the updates from Microsoft Catalog and update manually. Search for relevant KB in the Catalog.
Microsoft Catalog -
https://www.catalog.update.microsoft.com/Home.aspx
4. If above doesn't work - Share Setuperr.log and Setupact.log from
C:\$Windows.~BT\Sources\Panther - This log is mandatory for analysis
AND
C:\$Windows.~BT\Sources\Rollback\ - This log is not mandatory but useful for analysis
Note - These folders may be hidden, so you will have to do File Explorer > View > Options > View tab > Select Show hidden files, folders and drives.
Zip them and upload them to Onedrive and share the link here.
Do let me know if you have any more question or require further help.
