Default Muscle recruitment solver

ERROR(OBJ.MCH.MUS4) : C:/U..s/t..k/D..p/A..3/AMMR/A..n/E..s/S..l/SitUpModel.Main.any(70) : Study.InverseDynamics : Muscle recruitment solver : solver aborted due to singular KKT matrix.

Hi dear Sir I am facing these problem whenever I tried to change number of steps from 51 to 5 or 10 please help me out sir.
