Game stop working on load in Mapping

So I have had this error with my map where the game will stop working while the map is loading so i'm wondering if anyone knows a fix to this, This error is from the console.txt after the mod has crashed Thanks.

I know I can remove stuff like sounds, models etc.. that are not getting used but that does not always seem to help that much.
