Build Error - First Argument Must Be Text / Error in


When trying to build a model, I get the following error (with certain specific MATLAB versions only):

The error might be due to a bug in the Speedgoat I/O Blockset, as explained in this MathWorks answer. Please go to the Speedgoat website and update the I/O blockset toolbox.

For MATLAB 2022a, updating to version 9.6 solved the issue.
