The jacobian matrix evaluated at the steady state is complex

I am trying to run a DSGE model.But Dynare reports an error: The jacobian matrix evaluated at the steady state is complex. Does that mean the error come from the initial values selected?
Another question: how can I delete the problem about “sporious convergence”?
I attach the code.

Thanks in advance

Search the forum, there are lots of posts on the steady state computation.

Best,
