Hi @Piraisudan Rajendran,

You are receiving the error log ‘Failed to start with error, code = 16, message = license checkout failed’. You can leverage the following MATLAB answer to diagnose the issue:

License error code 16 could also mean that the MLM daemon path is invalid.

Check your $MPS_INSTALL/etc/license.dat (if Windows, $MPS_INSTALL\etc\license.dat) file and DAEMON MLM path is correct. If you're using Linux, this path would be:

DAEMON MLM $MPS_INSTALL/etc/glnxa64/mlm 

In case of Windows, this path should be:

DAEMON MLM $MPS_INSTALL\etc\win64\mlm.exe 

Hope this will help!
