Problemes with Matlab compiler

I have a srcipt that uses parfor. I have no problems using Matlaba compiler 2021a.

BUt, when I change thse lines (CASE 1):

load('datos tiles/data_tiles.mat')

parpool('local',p)

By (CASE 2):

myCluster = parcluster('local');

myCluster.NumWorkers=p;

myCluster.NumThreads=threads;

parpool('local',p)

The script runs with no problems, but the Matlab compiler is not working. Here p and threads are a variables define in data_tiles.mat, I'm not adding that .mat in the compiler files (in case 1 this works with no problem).

In fact,if a try to compile several time, differents error meseges apears

the log file:

1)Why there is a problem with the compiler when adding those lines?

2) Why the los files changes when repeting the process several times?
