How can I work around the limitation that code generation with the S-Function target is not supported with Initialize Function blocks in Simulink R2023b?

I am using Simulink R2023b. I am using the S-Function target file "rtwsfcn.tlc" to generate an S-Function from my model "CodegenModel.slx".

The model "CodegenModel.slx" uses an "Initialize Function" block. When I try to generate an S-Function from the model, I get the error

Code Generation using the rsim, asap2 or RTW S-Function targets are not supported in models such as 'CodegenModel', which contain Initialize, Reset or Terminate Function blocks

How can I work around this error?

To work around this error, you can generate a Protected Model from your Simulink model that uses "Initialize function" blocks instead of generating an S-Function. Protecting models is a preferred solution for IP protection, and you can place protected models in other Simulink models to reuse your component.

For more alternatives to the S-Function target, see the note on top of the documentation page, "Use S-Function Target for Model or Subsystem":
