Try the solution in: "syms", "sym", and "mupad" functions cause MATLAB to freeze (link).

It didn't help I have Matlab 2018 a and still does the same

[Star Strider]

The update worked for me in R2018a.

You most likely need to contact MathWorks for help. Click on the Contact Us link in the upper-right corner of this page and use the Contact Support option. Copy the URL to this page and paste it in your message so you don’t have to describe what you’ve already done.

Also, type ver in your Command Window so you can also copy that output to the correct pane in the Contact Support page.

Plain release R2018a is not sufficient. You need to have release R2018a Update 1 or later. When you run ver as Star Strider suggested, if it does not show Update 1 or later, install the update.

@Steven Lord — Thank you for the clarification.
