How can I get past error “an error occurred applying the software update” on my Mac after attempt to install Big Sur?

If you have downloaded the full installer and you are having an issue, reboot into safeboot mode than launch the installer from a Safe boot mode.

The installer can be found in your /Applications/"Install macOS Big Sur.app"
