This is a complex mod and I have experienced crashes that can softlock your world by crashing again everytime you open it.
One such issues can occur when you select a certain block that is incompatible with the current version of the mod.
Restarting minecraft without this mod and unequiping this block should solve the problem after which you can restart again with the mod.
However to be sure you don't lose your world, I suggest making a copy of the world folder in your '/.minecraft/saves/' folder.
I will continue to try eliminating all of these issues but every new feature has the potential to cause more of these in hard-to-find edge-cases.
