Is there any way to load libraries into a project dynamically through AS3 or during publish only?

Basically my library is just too big for adobe animate to handle in one piece. I need to break it into multple pieces and have it either load through AS3 or load only during publish. Adobe animate literally runs out of memory and the whole program turns black after only a few seconds of editing anything in my library. Loading the library with the "open external library" doesnt work, it crashes everytime because my library is just too big.
