Also uninstall any antivirus and "cleaning" apps before trying installing again.

Further, you need an Apple disk installed to upgrade to Monterey since the upgrade includes an update to the Mac's firmware. That update looks for an Apple disk and write to the dick to do the firmware update. The install will terminate or freeze if no Apple disk.

Are you using Filevault to encrypt the disk? If so turn it off and then try after the de-encrypting is complete. That can take many hours.

Some users have problem with skipping upgrade versions and even not updating to the latest version of Big Sur. Some users have experienced problems by skipping upgrade,es like going from 10.15 to 12 (Monterey). I recommend incrementally upgrading to each sequential version. To find older versions:]
