Errors in Assembly

Hello, I had a question I cant seem to find an answer for on my own. I design large pieces of machinery, and after all of the engineering is complete I add ocnfigurations to the assembly and supress system within the machine in order to narrow configuration into specific systems of the machines for exmple hydraulic systems, engine system, cooling system etc. When I am supressing parts now, SW just crashes. I have been doing my assemblies htis way for a while and have never had this problem before. Any help would be much appreciated.
