I would suggest running an xml validator on it, and then hand-editing to
remove half the layers (saving original of course :-) and so on, to see
if you can figure out what is provoking the crash, and keep the other
98%.

I find it vastly unlikely that this is a bug with .14.

You also might recover the project file from backups and diff those
against the current one.
