The latest update (Catalina 10.15.6) does not install on my MacBook Air running Catalina 10.15.4

My 2015 MacBook Air is currently running Catalina 10.15.4 without any issue. I have a notification that the latest update to Catalina 10.15.6 is available on my Mac. When I click "Update", it restarts and go back to the login page. Update not installed and no error message. I made sure I had more than 30GB free space on my hard drive.

MacBook Air 13″, macOS 10.15

It can be updated by downloading the Combo Update here https://support.apple.com/kb/DL2048?viewlocale=en_CA&locale=en_CA

Would suggest having a full TimeMachine Backup and a bootable Clone of the computer Before attempting the update. That is just if something goes sideways
