Hi,

The particular error might indicate that MATLAB is not able to locate or read your MATLAB preferences directory. This could be due to a setting or variable on your system which is causing MATLAB to look for your preferences in a location where you do not have read access.

Typically this happens due to running a configuration script for MATLAB such as ‘config_matlab.sh’ which attempts to set your preferences directory to a non-default location where you do not have read or write access. You should start by removing the portion of the script which sets your environment variable.

I hope this helps you to resolve the issue.

Regards,

Shivam.
