Hi, I am Dave, I will help you with this.
With a large feature update like version 24H2, the roll back option is only available for 10 days after the upgrade, after that, the only way to go to version 23H2 would be to create a bootable Windows USB and use that to clean install version 23H2.
However, the problem with that now is, that on the Microsoft website, they now only provide the ISO and USB for version 24H2, they no longer provide a download for version 23H2.
