Failed to validate a local parallel cluster in MATLAB 2021b

When I try to validate the local cluster I have an error, this is the report of the validation.

Failed to run the DisarmableOncleanup callback due to the following error:

I have searched for a solution and tried this code, but didn't work.

distcomp.feature( 'LocalUseMpiexec', false )

And I tried restoring the matlab path but also didn't work.

Does anyone know how I can solve this problem? Thanks in advance!

I would suggest contacting Technical Support ([e-mail]).

Hi guys, I got the same problem, did you find the solution?

Did you guys find a resolution to this problem? I'm seeing the same issue.

[Raymond Norris]

@Heinz Miranda, please contact Technical Support ([e-mail]).

Actually, In my case the issue depended on my surname, which contains an accent mark (I am Italian, BTW). As this was also in my home directory path, and the latest release of Matlab being unable to handle it (differing from previous releases), I had to change my home directory path (which actually made a few other apps to malfunction). In the end this was filed as a bug to solve - and I am afraid this is not helpful to you.

Nevertheless, the Matlab team also suggested me this workaround (after I changed my home directory path - never tried it):

They have provided an alternative workaround which is to start MATLAB with a modified license path using the -c argument. The underlying issue is that the license path contains a non ascii character (the ò) by pointing to the license in a location without that character you will be able to continue using PCT with no issues:

How do I force MATLAB to ignore the LM_LICENSE_FILE environment variable?
