is amazon making new drm?

That is odd... Please try re-downloading book, ensuring that the Kindle software you are using is the same you are downloading with and that you can open it in Kindle... Other than that, not sure. It looks like you don't have correct credentials loaded, as new DRM would have given error 32...

somehow fixed the issue by typing the command manually, instead of copy pasting it. sorry for bothering you 🙇
