Hello guys! I am trying to run an extended version of a New Keynesian model with search and matching frictions - featuring incomplete markets (Tractable HANK, i.e., degenerate distribution across types). I cannot understand why the Blanchard Kahn conditions are not satisfied (indeterminacy). I have attached the relevant files. Thank you very much in advance!

That is hard to tell. Does the model without SAM work as expected?
