You will need to disable KFX downloads. Or go back to no later then Kindle for PC 1.26 and install the KFX Input plugin. See this post for details: https://www.mobileread.com/forums/showthread.php?t=283371

Thanks, i didn't disable kfx cause i saw that the file that was downloaded was .azw, my bad sorry. Anyway worked fine, thank you so much.

It was KFX format in your log. AZW is a generic Amazon book extension that the Kindle app uses regardless of format.
