this is a LaTeX error has nothing to do with LyX.
And, LaTeX does page by page, so the size of the project doesn't matter.
It can be as easy as a missing } or something.
I would start looking at the log file.
If that doens't work, half the project, if it has the error, half it
again, If it doesn't use the other half. You do that until you have
located the error, which you then correct in the original project.
Version Control and backups are your friend :-)-O
