I could guess, this is because you donot have 'Symbolic Toolbox' installed in your MATLAB. Can you run the following command to check:
status = license('test','symbolic_toolbox')
If status is not 1, then you need to install the toolbox to proceed.
I hope this solves your issue, if not this might be due to the issue with MuPAD engine.

Thank you so much for this answer. The symbolic toolbox was not working on Mac OS Ventura even though the directory /var/tmp existed. Once I set the directory permissions for /var/tmp as follows:
sudo chmod 777 /var/tmp
and restarted matlab it finally works again.

These days the mupad command has been removed from MATLAB.
