I had the same issue with a brand-new MacBook Air. What have you tried?

The work-around for me was to restart the Mac in safe boot mode, and run the upgrade check again there.

Be prepared for a long wait: the download was 12.15GB (vs. 6 - 7GB when I tried normally), and the software then took 4 - 5 hours to install once downloaded. It did work though!

Follow previous advice First but an observation " Hi I have a 13inch 2017 MacBook Pro currently using macOS Big Sur version 11.6.5. "

Sometimes the issue of upGrading while running an outdated previous very of macOS can have consequences such as what is happening to the computer right now.

The current version of Big Sur is 11.7.1

Usually that error can be fixed by trashing the old "Install Ventura ..." from /Applications, rebooting (maybe to safe-mode) and downloading a fresh installer.
