I have the same problem, except for MacOS Catalina 10.15.1 for version R2019b. See https://www.mathworks.com/matlabcentral/answers/496220-matlab-2019b-installer-does-not-install-on-mac-os-catalina.

This does not solve it. I have the same problem for Matlab R2019b. See https://www.mathworks.com/matlabcentral/answers/496220-matlab-2019b-installer-does-not-install-on-mac-os-catalina.
