When running the program, debug is displayed

I guess your beam identity is wrong (or flipped) did you try to flip them?

> I've been using MadGraph5 to generate the z boson and the Higgs processes recently. I am using the sm model.I defined the w boson, z boson, and photon as vxm and vxp, and made vxm and vxp produce z boson and Higgs particle. I only changed the collider to Muon Collider on the basis of the original, and the other values were the default values, but bugs were always displayed during this process. The following is the statement I entered and the content of the error. Can you help me see where the problem is ?
