Error Compiling to Kindle

Hello! I’m getting an error I don’t understand when I try to compile to Kindle. All other formats work just fine.

I thought maybe it was a disk space issue, but I tried cleaning up my hard drive and rebooting. It didn’t help.

I have this version of Scrivener: Version: - 14 Nov 2019

Any assistance you can offer would be very appreciated.
Best regards,

I believe I’ve solved this too. I reduced the size of the images and that seems to have allowed the Kindle compile to go through.
