Big Sur Software Upgrade Error

Hi, I have been trying for a little over 24 hours to update my MacBook to Big Sur Software and appear to be stuck in a loop, without being able to get this finalized. See pictures below.

MacBook Air 13″, macOS 10.15

Force shutdown via Power Button and disconnect all external drives. Plug into charger and restart holding Shift key immediately at startup. This is Safe Mode which does a Repair Disk, clears cache files and load only Apple Default Software - so loads slowly - Normal. This may allow the upgrade to complete the installation.
