Zymkey problem encryption phase 2


I’m following the steps to put my Raspberry pi4 b, to production mode.
My problem is when I try to encryption SD card using the tutorial " Encrypting Root File System with Zymkey4". When Raspberry reboot after phase 1 completed, raspberry boot and nothing more happen (OS boot normaly). Any script to phase 2 start… After that, if I reboot the raspberry, I can not boot anymore. Please see the screen: “waiting for SD card (settings partition)”
