I don't use Scrivener so it is difficult to say and it is too bad if Kindlegen error message is blank. Regarding EPUB and MOBI/KF8, they are pretty much the same, the compilation is different. I have limited the HTML I use to be compatible with both formats. However I have 2 slightly different CSS, one for each format. OPF files are the same except for the cover part. And I remove reference to the HTML cover in the NCX file for MOBI/KF8. I am not sure this helps you that much. What I can suggest is to start with a minimalistic eBook, one or 2 chapters with limited text, limited style, no custom font, no images, etc. and check what happens. If it works, implement progressively more chapters, more text, more style until you get your blank error message. You will then know what causes the problem.
