How are you booting to Ventoy - UEFI64 or BIOS/Legacy?
How did you make the ampe.iso file - download from internet option or build option?
Did you try the Ventoy wimboot option (you may need to add the plugin).
I tried both types of ISO on real system in both UEFI64 and BIOS mode and it seems to work.
The ISO does seem odd though in that it does not seem to have the normal \EFI\BOOT\BOOTX64.EFI boot file.
