In this case, there's usually an issue with particles (as mentioned above).
This being when the particles have somehow made copies out of themselves,
causing them to have _0 and/or _1 behind the actual particle name.
If you go into the folders and search for these, you might find one or two which should be deleted.
If you don't have this issue, but it continues to crash, let us know.
Goodluck.~
