i am having an error while trying to rebuild an assembly

hay

i am having problem with some assemblies that i work with casualy.

i loads the assembly and solidworks asking me to rebuild, when i try to rebuild solidworks crashing.

it showing me that three sub assemblies need to be rebuild, and if i open them each one individualy i have no problem to rebuild.

but if i try in the big assembly it crush.

is there any way to rebuild slowly one step by another so i could find what is wrong?

is there any way before rebuilding to see what is about to be rebuild?

thanks
