The crash actually looks like an issue with Tropicraft, try removing it and if that fixes it, I'll file an issue on their issue tracker (I can already imagine what the issue might be).
As for Millenaire, I cannot see what's wrong from the errors in the log and the 1.12 version of the Millenaire mod seems to be proprietary, meaning I cannot look at its source to find out what's wrong. You'll have to complain to the developer(s) of the Millenaire mod directly, nothing we can do here.
