Can't start parallel pool in Matlab R2021b, it always hangs at jobs creation

When trying to start a pool for parallel processing, Matlab gets stuck, actually after giving a "parpool" command it will hang without giving any error message and it can be closed only forcedly. When trying to run a validation in the cluster profile manager, it passes the first test (Cluster connection test) but it will hang for ever while trying to perform the second test (Job test) and will not arrive to start the next three test (the SPMD job test, the pool job test and parallel pool test). Below the validation report and the Matlab components installed on my PC.
