Sir,I want to ask you some question.The following is my Dynare code, but it can not run the result, the problem seems to be in the steady state above, can you ask how to solve it

You need to correct your model. For example,

log(r) = rho_r * log(r(-1)) + phi_pi * log(pi(-1));

pi = P/P(-1);

are inconsistent with r=1/beta from the Euler equation. Also, the last equation implies a unit root in the price level, meaning there are infinitely many steady states.

Sir，I have corrected the last part of the code, but there is a problem in the steady-state solution part, so that the result is still not obtained.In particular, there is a contradiction when manually solving the equilibrium solution, but the same method can be obtained and operated normally from other journals, phi variables and D variables.

Are you sure that the steady state values you set in the Taylor rule are the correct ones?
