Losing my mind

I have tried using the older android app, the kindle for PC 2.4 app with no success. I have also tried the latest release and autobuild release of DeDRM without success. I have tried exporting and using the android app files onthe latest kindle app(.kfx and .ast voucher) without success.

At this point i'm not sure if what i'm doing is wrong or there is some sort of new drm on my book (isbn 9780137594177) I beg for some guidance here.

Windows 10

Calibre: `7.1.7`

Kindle: `2.4.0 PC`

DeDRM: `10.09`
