Symbolic Math Toolbox error

When I type:

syms k c

at the command line, I get the following error:

Error using mupadmex
Error in MuPAD command: .

Error in sym>tomupad (line 1250)
    S = mupadmex(numeric2cellstr(x));

Error in sym (line 217)
                S.s = tomupad(x);

Error in syms (line 232)
defined = sym(zeros(1, length(args)));

Perhaps it is an installation issue, but it used to work fine. Any ideas?

I have the same Error, seems like a Apple/MAC Issue.

There is an error that looks like this that shows up only on Catalina.

Note: R2019a is not supported for Catalina.

The solution was to upgrade to 2019b as 2019a does not support Catalina OS. Thanks everyone for the help.
