Reinstalling macOS after erasing - getting error

Sounds like you plan to keep the Mac? When setting up the Mac to sell you only want to get to the point of the OS being installed then when it asks for user name you stop and turn off the Mac. That way the new user will enter their name and start as a new machine. If it gives you the OS as Monterey then use that level.

How to reinstall macOS - Apple Support

Scorched Earth Method 

This method will WIPE ALL Data and there is No Recovery - Period.

>> Only works on Intel Based Apple Computer <<

To perform this action will require booting from a Bootable Installer. 

The Bootable Installer can Only be performed on an Apple Computer 

This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer. Example : Bootable Installer of Big Sur would have to be done on a computer that Qualifies to run Big Sur.

Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can not be used.

Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.

Extra Special Notation regarding the Touch ID equipped Apple Computer.

 About Startup Security Utility and Must Enable from Recovery Mode the ability to boot from External Drive Before Attempting 

1 - Shutdown computer and disconnect all external drive Except the newly created Bootable Installer.

2- Restart and immediately hold the OPTION key until the Startup Manager appears and choose the USB Drive. 

3 - It will present options >> Disk Utilities >> View >> View ALL attached Drives. 

4 - Choose the Upper Most Drive ( not the volumes indented and list below ).

5 - The drive normally is called Apple Media or Apple SSD - that is the drive to Erase and format as APFS with the GUID Partition Map. This applies to macOS 10.14 Mojave and above. 

5A - Formatting for macOS 10.13 High Sierra and below requires HFS Journaled with the GUID Partition Map

6 - Once that is done >> backup out of Disk Utilities and choose install macOS. 

7 - Follow the prompts and it may automatically reboot several time.

If you attempted the " Scorched Earth Method " and this " Volume MisMatch" error occurred ?

Any After Market RAM installed on this machine ?

Failing or Failed RAM Modules can present this type of MisMatch error.

If After Market RAM is involved this is a tedious exercise to remove one Module and Test. The remove another Module and Test again

Basically a trial and error to confirm which Module(s) is / are the cause.

Now, have a few links I have collected on RAM Module " Volume Mismatch "

Perhaps from there you can see if their issue lines up with your machine issue

Please help - Terminal.app keeps crashing upon reopening - macoS Monterey version 12.4

Volume hash mismatch, cannot reinstall MacOS

Monterey rev 12.4 - Hash mismatch

Volume Hash mismatch

Strange Disk Space Issue

If you have erased all your info and are trading it in I would not worry about the install. Apple will redo the initial new owner install on any Mac that they get anyway (they would not trust the previous owner anyway).

Sounds like it was not erased and formatted correctly to APFS, GUID partition. When starting in recovery mode, use Disk utilities, then click on top most directory of drive then erase and format and try again. It should not see any "corrupt" file as nothing is on the disc.
