Dynare mistake: One of the eigenvalues is close to 0/0 (the absolute value of numerator and denominator is smaller than 0.0000! If you believe that the model has a unique solution you can try to reduce the value of qz_zero_threshold

Hi, I have met a big problem. It confused me a long time. Could you please help me?

I can only give you the generic advice: try to simplify the model to see where the error comes from. Pay particular attention to timing errors.
