This very much looks like something is wrong with the MATLAB installation on your system, or perhaps some code on your MATLAB path is interfering with the correct operation of Parallel Computing Toolbox. You might try using restoredefaultpath to see if that fixes things. If not, I suggest contacting MathWorks support.

Do you have other versions of MATLAB installed? If so, which? Had your run parpool successfully on those version(s)?

One suggestion I have is to delete your MATLAB R2020a preferences directory (which may not be desireable) since it sounds like something may have gotten corrupt. You can find the preference directory by calling prefdir.

Cluster report.txt

I managed to delete preferences file.when i restart matlab,preference file is created again,and i can start parallel pool.When i shut down pool and start parallel pool again,it throws same error again,like

"Error using parpool (line 139)

Parallel pool failed to start with the following error. For more detailed information, validate the

profile 'Profile_Deena' in the Cluster Profile Manager."

I tried to validate in pCluster profile manager,then it shows this:

When i clicked show report button at bottom,it shows the report i attached here.

If you can help,kindly reply
