Mac 10.15,7 update failed. Getting "Service Connection Invalidated!" in log file

Since the release of the update of mac 10.15.5 I can't install it on my macbook pro. After downloading the whole thing and going on upto almost the final point of installation process it's saying "An error occurred while installing the update. Trying again may fix the problem". I have already tried umpteenth times but it is in vain. Also tried to do the same with downloading files directly from apple website, in Recovery Mode, and erasing the hard drive and then installing fresh copy again. Getting the same error. Please help! It is like so long I am trying the same thing over and over again with no hope. Here is the log file details

At this point, suggest downloading the Full Catalina Installer from the Apple Apps Store. Stop there and do not let it start the installation. Copy the newly installed App ( Install Catalina ) in the applications folder to a safe external location. It can be used to create a Bootable Installer on USB at a later time.

Reboot in Safe Mode ( Shift Key at startup ) and then run the installer. Hopefully it with replace / update any missing or corrupted files.

Make sure the internal drive has at least 20+ GB of Empty space , some unconfirmed cases say 40 GB empty.
