Starbound not loading when using mods

Everytime I try to get on starbound after i mod it, it starts loading, with the protectorate logo in the bottom right corner, but then it stops, saying a huge thing, that i can't copy and paste,but the top says

Fatal Error: Access violation detected at 00007FF688752746 (Read of address 00000000000001420

Then it goes on and on, saying something about the CharCreationPane and the TitleScreen. Help.
I need this figured out ASAP because I have to stream soon.
