Hello,
Maybe this book is a Kindle Unlimited book or a newly published book in 2023, so it requires the latest V1.40 Kindle app to download it.
If it is a Kindle Unlimited book, I'm sorry that our Epubor software does not support decrypting and converting this rented book.
For the ebooks published in 2023, here are 2 solutions to solve this problem:
1.If you have any Kindle device (kindle fire or kindle e-ink device) registered with your Amazon account.
Please download the Kindle books via "download and transfer via USB" and then remove kindle drm with epubor ultimate.
Here is the detailed guide: https://www.epubor.com/how-to-remove-drm-from-kindle-kfx-ebooks.html#meth4
2. If you don't have a Kindle e-ink device, we recommend our new product Kindle Converter to decrypt and convert the Kindle books published in 2023. please learn more here:https://www.epubor.com/kindle-converter.html
