You can ignore this warning during initialization. Also, you can add more iterations in the hybrid initialization.

Yes you can ignore the warning, but that the invicid solver is not convergving below 2e-3 and actually increased from the last iteration(s) is a bad sign. It is likely caused by an incorrect setup. If this number was 1e-8 or something and slowly sinking it would be ok to continue. Remember what an initial condition is. It is a “guess” of the solution and a better initial guess will require fewer iterations to reach a steady solution.

In your case I would really examine the solution after clicking the hybrid initialization. Is the flow moving in the correct direction? Are the things you want to be walls actually walls? Are your interfaces (if you have them) correctly defined? Often the hybrid solver can help us indentify these problems before we go to the full solver.
