Error while using syms command

Matlab worked great for me until i updated my computer. After that i get an error each time i try to use the syms command. This is the 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)));

What can i do? My computer is a MacBook if that helps.

This is a known bug related to Catalina. If I recall correctly there is a workaround available, but before looking for that I would recommend updating to R2019b Update 4.

Updating to R2019b fixed it, thank you!!
