I checked the log file CMUpdate.log in the directory below. There was a lot errors seemingly in validating the files but nothing that I can make out to see what caused why it had the issues.
C:\Program Files\Microsoft Configuration Manager\Logs\
To reinstall the components, you would perform a site reset.
From MS, when a site reset runs at a central administration site or primary site, the site: (https://docs.microsoft.com/en-us/sccm/core/servers/manage/modify-your-infrastructure#bkmk_reset)
- Reapplies the default Configuration Manager file and registry permissions
- Reinstalls all site components and all site system roles at the site
The update should be in this directory below and run the splash.hta to bring up the menu.
C:\Program Files\Microsoft Configuration Manager\cd.latest\
Click Next and select the Reset site with no configuration changes.
You can view the log from the View Log button during the progress.
