I am unable to share the full model but I've attached snippets of the model that is giving me issues. The error_model is the one that throws the mentioned error. The working_model does not throw an error and is able to be fully generated by HDL Coder.
Thank you!

This is an unexpected internal error. Reported to the development team.
Can you let us know what version of MATLAB / HDL Coder are you using?
