Still not working on NEC CM4 with version 1.32

Hmm, I'm not sure why this would be different from the normal pi4. Have you tried changing the sd controller to the arasan, "Device Manager"->"Raspberry Pi Configuration"->"SD/MMC configuration"->"uSD/eMMC Routing"

Do you have a serial port what does it print during boot?

I assume this is windows doesn't boot, not that uefi doesn't get windows starting...

Those screen I got. Twice blinks green text on top left corner (no photo) and same with arasan or classic settings.

also there I got some bluescreen: interrupted not handled (no photo)

and last image is serial debug. but this LCD NEC has RS232 connector wired inside and it can display on LCD screen. Not wired outside :-(

If you hit esc, do and go into the boot device area, do you see windows listed, how about if you drop to the shell, and start the boot manager directly via bootaa64.efi.
