I followed the very simple and straightforward guide to write an S Function Builder Block here https://www.mathworks.com/matlabcentral/mlc-downloads/downloads/submissions/39354/versions/10/download/zip/DriversGuide.zip and I get the following error when clicking the Build button:
Error using fopen
The file name contains characters that are not contained in the filesystem encoding.
Certain operations may not work as expected.
I have r2018a.

This problem does not occur when the exact same thing is tried back on r2017b.
