I understand that you are facing permission issues with MATLAB on your machine.

From the error message, it looks like you have installed MATLAB on a Linux machine. To get rid of the error, you can grant permission for that file specifically or for the /home/draadel/.matlab/R2021a directory. For this, you need to follow the steps below:

• Open a Terminal by pressing Ctrl + Alt + T on your Linux machine.
• Execute the follwing command: sudo chmod -R 777 /home/draadel/.matlab/R2021a

For more information, you can refer to a similar MATLAB answer on MATLAB permission error in Linux Ubuntu 18.04

Note that it is common for pem files to not have read access. They are used to contain security information and making them unreadable without privileges increases their security.
