How to fix such error which enable me to open my assembly? I can try to load assembly with structure only but then it is not possible to load components that are source for link bodies in that top level assembly.
Try open the assembly Structure Only. ( i assume that you have a number of wave linked features in the assembly.) Then go : Edit - Feature- Playback... click the "continue" button + OK.
Run Part cleanup.
then try open the components.
