Errors in steady-state solving"One of the eigenvalues is close to 0/0 "

Hello everyone,
I get the following error when I run the code:

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.

I don’t know where the problem is, can someone help me?
The code is here
model.mod (9.4 KB)

Check your model and in particular your timing. E.g.


looks strange. In general, start from a simpler model. Debugging such a large model is hard.
