An Error:The steady state has NaNs or Inf

Dear all:
I’m a beginner in dynare, and I found an error when running estimate_bygdp.mod file: “The steady state has NaNs or Inf.”, but I checked the answer in the dynare forum that it was possible that the steady state calculation was wrong, so I rechecked my steady state, found a small error and corrected it, but when I ran the estimate_bygdp.mod file again, it still said: “The steady state has NaNs or Inf.”, so whether my model has an error or a problem with parameter assignment, please answer it. My steady-state value calculation is calculated in the external functions: SolveSteadyState_bygdp.m file and FullSteadyState_bygdp.m file. I have uploaded the relevant command, please help take a look.Thanks!
