i put back in those mods i took out earlier tough. exept for addition game settings. that one gives a error, so the standalone mods doesn't open on savegame start up.
I don't see any obvious issues. It might just be a painful process of keeping relight, then adding in 5 mods at a time, loading, seeing if crashes or not, and keep going until you find the conflict. Maybe one of those mods alters one of the same files relight does but I can't tell for sure. If you find the conflict in question there's a possibility a fix could be implemented, workaround, but you might just have to make a choice which mod to use if the conflict is too great.
