Assuming your .bib file does not contain state secrets, how about the 
following? Create a new LyX doc (MWE) in which you just cite everything 
that gets cited in the actual document. We don't need headings, images, 
text etc., just the citations. Try compiling that. Assuming the same 
problems occur, post the LyX MWE and the .bib file and let our resident 
biblatex experts (of whom I am decidedly not one) try for themselves.
