I solved this error by replace the multiply operation from Ctxt1.*=Ctxt2 to Ctxt1.multiplycation=Ctxt2.But I'm not very clear about the difference between the two operator.Relinearize operation is the only difference between them?

Yes, relinearization is a critical part of the proper multiplication, unless you are doing something much lower level. It could be argued that the *= operation should not be exposed so readily to users. For more you can read "Efficient Fully Homomorphic Encryption from (standard) LWE".
