KRD ISO changed to using Debian, so if you use a persistence file, KRD 2018 required the casper version of the persistence file - but KRD2024/2025 requires one of the 'persistence.dat' group of files to be used (which contains a persistence.conf file inside it).
Also, you will need to modify the kernel parameters to include the 'persistence' parameter on the kernel line in the boot menu.
The table in the Documents on the Ventoy site omits this and just shows KRD2018+casper as an example.
