You need to rename the system snapshot to a name that is not named com.apple.os.update-*, such as orig-fs or it will try to restore rootfs.

Where is the snapshot located in the rootfs?

it's a property of the APFS volume responsible for the rootfs

Fix:
Mount the rootfs and follow these steps to rename the snapshot (can be renamed to anything else such as "orig-fs"): https://support.apple.com/en-vn/guide/disk-utility/dskuf82354dc/mac
