MacOS Catalina 10.15.6 Update: An error occurred installing the update

Hello I have a new MacBook Pro16'. Whenever I attempt to install the latest update I get the same error "An error occurred installing the update- You can try again to complete the installation".


I've tried again over many weeks and get the same error. I have also attempted to install in safe mode and get the same.


Assistance would be greatly appreciated.

MacBook Pro 16″, macOS 10.15
