2017 MacBook Air stuck in loop: Acts like it installs Monterey but stays on Big Sur

Hello Apple Community,

I have a 2017 Mac Book Air, recently reset to factory settings and it performs just fine. There is 79.38 GB of 121.33 available on Hard Drive. System Updates shows I can update to Monterey and I can I click through the prompts to download Monterey Installer. When I run the intaller, it acts as if it has installed Monterey and will restart, but always back in Big Sur. No error messages. Just back to Big Sur as if I simply restarted the computer. System Updates continues to show I can update to Monterey. I can run the Monterey installer over and over, stuck in this loop.

Any guidance on how to get the Monterey OS to install in this situation would be appreciated!

MacBook Air 13″, macOS 11.7

Have you tried it in Safe Mode yet?

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

Are you running any VPN, Anti-Virus, or Cleaning apps?
