whatever this mod is, that's what's causing the error, and so you know somewhat what to look for next time, usually there will be a section near the end of the crashlog with all the mods listed, it looks like this:

as you can see it tells you what each letter before the mod names means, you can see the one that errored for you (I put it in bold). not all crashes will show this but if it's an initial boot up or "first run" then this is the first place to check.

I hope this helps you for future modding problems, I hope I did not come across as rude or sarcastic, just trying to help.
