The error you reported is not caused by MultiOS-USB. The configuration file lacks information about the location of the ISO image, which is passed as a kernel parameter, e.g.:

• iso-scan/filename=${iso_path}
• findiso=${iso_path}

Example:
/boot/grub/grub.cfg in LMDE6 - does not boot:

menuentry "Start LMDE 6 64-bit" --class linuxmint {
	set gfxpayload=keep
	linux	/casper/vmlinuz  boot=live live-config live-media-path=/casper quiet splash --
	initrd	/casper/initrd.lz
}

/boot/grub/grub.cfg in Linux Mint 22 - boots:

menuentry "Start Linux Mint 22 Cinnamon 64-bit" --class linuxmint {
	set gfxpayload=keep
	linux	/casper/vmlinuz  boot=casper username=mint hostname=mint iso-scan/filename=${iso_path} quiet splash --
	initrd	/casper/initrd.lz
}

I found a similar problem in the Linux Mint project: linuxmint/linuxmint#635. I think you need to report the problem there.

Temporary workaround:
use config: config_priv/lmde/lmde.cfg-example and remove -example from filename

Brilliant, thank you. Your example configuration file works. I shall follow-up with the Mint team.
