I get this error when I run my code with Matlab 2018, the same code works fine with Matlab 2017, can you please let me know how to solve this issue?

Invalid MEX-file ‘/Users/aminghazanfari/Documents/MATLAB/cvx/lib/cvx_bcompress_mex.mexmaci64’:

Did you try consulting MATLAB. It looks like MATLAB issue not CVX.
