Currently there is a bug which stops MATLAB License Manager Error message windows from appearing. To find what error is causing MATLAB not to function launch MATLAB from a terminal window using a command such as the one below.
/Applications/MATLAB_R2019b.app/bin/matlab
This should output the License Manager Error, which you can use to determine the root of the issue.

Same problem for me; also double clicking on a .m file will not open Matlab.
Matlab only opens if I type /Applications/MATLAB_R2019b.app/bin/matlab in a terminal, but it does not output anything regarding the error.
