crashes when i try create a world

I'm trying to make a playthrough (singlepalyer) with the following mods: calamity, calamity-wrath of the gods, calamity-hunt of the old god, infernum mod, catalyst mod, remnants and a few more smaller mods for improvements. I've tried disabling every mod other than the big contents mods from above but every time i start generating the world it'll freeze towards the end of the generating and completely crashes/ closes my game I don't even get a crash error message. if anyone has any suggestions on what i can do to fix this issue without removing a mod it would be much appreatiated.
