If admin account name is changed and converted into standard account , enter in single user mode .

See this article Start up your Mac in single-user mode or verbose mode - Apple Support

Execute this command .

mv /var/db/.AppleSetupDone /var/db/.OldAppleSetupDone

Then press enter key after that .

exit

Restart the Mac , then it will prompt language then create a new user account .

Note : In the first terminal command there is space after mv and also space after AppleSetupDone .
