Why won't this optimization code run in Matlab R2018a?

I generated the following optimization code for a mechanical engineering problem a few years ago in Matlab R2013b, and it still solves in that version. But, it will not solve in version R2018a, and it causes Matlab to hang. I have run the code compatability report, and that check found no syntax concerns, errors, warnings, or improvements. Any guidance you can provide would be appreciated.

Have you installed the update packages for R2018a?

No, I had not. That resolved the problem. R2018a now solves the problem. Thank you for your help.

Try installing with the update packages. And then you can try to solve this problem on optimization: https://www.mathworks.com/matlabcentral/cody/problems/44718.
