Where are you seeing this internal error? From calibre KFX plugin?
Perhaps it is an issue with the ePub files in question. Do they pass epubcheck? If not, I think it can generate 'internal error'. For another 'opinion', try opening in Apple Books. It's pretty picky as well.
If you have brew (Mac package manager), you can install epubcheck with brew install epubcheck. There's a calibre plugin to run it.
if you don't have brew installed, here's how: https://brew.sh |
I see it first on Calibre during converison. When I check the conversion log, it says the problem wass Kindle Previewer 3. So I try to open a simple epub with Previewer and as expected, it also says there's an internal error. Its conversion log says nothing beyond this. But Kindle Previewer 3's crash log has something complicated. May be you can understand.
BTW, I am using the simplest test epubs. iBooks opens them without problem and they pass the EPUBCHECK...
I am not gonna be crazy for nothing. :/
[EDIT]: added epub file, Calibre and Kindle Previewer 3 conversion and crash logs
