How to fix parallel pool error Matlab2018a

I'm trying to run some simulations on my university's supercomputer but I get the following error for some of the jobs:

Error using gcp (line 49)
Parallel pool failed to start with the following error. For more detailed
information, validate the profile 'local' in the Cluster Profile Manager.

Error in nncalc.setup1>setupImpl (line 91)
    pool = gcp; % (Will auto-open pool according to PCT preferences)

Error in nncalc.setup1 (line 16)
[calcMode,calcNet,calcData,calcHints,net,resourceText] =
setupImpl(calcMode,net,data);

Error in nncalc.setup (line 7)
[calcMode,calcNet,calcData,calcHints,net,resourceText] =
nncalc.setup1(calcMode,net,data);

Error in network/train (line 357)
    [calcLib,calcNet,net,resourceText] = nncalc.setup(calcMode,net,data);

Error in train_network (line 29)
    [net,tr] = train(net, inputs',
    targets','useParallel','yes');%,'showResources','yes');%,'useParallel','yes','showResources','yes');

Error in main_train_nn_1outputs_scitech (line 26)
[net_thr, tr_thr, time_thr] = train_network(inputs(:, data_vector), targets(:,
1), trainFcn, hiddenLayerSize, train_size);

Caused by:
    Error using parallel.internal.pool.InteractiveClient>iThrowWithCause (line
    676)
    Failed to start pool.
        Error using
        parallel.internal.customattr.CustomGetSet/hSetAllowNonPublic (line 76)
        Cannot create 'Task1.in.mat' because
        'path/.matlab/local_cluster_jobs/R2018a/Job17'
        does not exist.

Any ideas on how to solve it? I never had this problem before and it only happens some times.
