It appears that a Stateflow chart in your model needs to generate code for execution, but MATLAB/Simulink is unable to write to disk. Perhaps you don't have write privileges in this folder? Try starting MATLAB with "Run as administrator" and see if that helps.

I have the same problem and I knew it was because I didn't have privileges. The problem is that when I run matlab as an administrator I am able to create the folder but the problem is that then matlab crashes. Then I restart matlab NOT as an administrator and (because the folder and the file were created without problems when I started it as an admin) everything runs smoothly.
What should I do to solve the problem?
Thanks.

I got a similar error and it said the identifier is useless, fopen cannot create a useful identifier. Anyone can help me with that?1572848883(1).png
