I have following settings to make org-mode export to PDF works better,
like export with src block syntax highlighting with "minted", and
support Chinese export with latex package "ctex" and specify default
font etc all stuffs.
I used to disabled org-mode startup preview latex fragments. Today I use
[C-c C-x C-l] to preview latex fragments, it raised error (I shorten the
very long error stack):
```

Here is a simple version config might reproduce my problem:

better image.
