If you were not using Linux, I would speculate that you might have a third-party function that is interfering with MATLAB operation, such as a function from SPM12's compatibility directories.
But since you are using Linux... well, the above is still possible, but it also becomes possible that you have an incompatible library file that needs to be moved out of the way... something like libC.so.6 . I am not qualified to chase down such problems, so you should ask Mathworks Support.

The error may be fixed by setting aside the libfreetype.so.6 in <matlab_root>/bin/glnxa64/. Run the following command:
cd <matlab_root>/bin/glnxa64/
mv libfreetype.so.6 libfreetype.so.6.old

Hi,
While launching MATLAB, if you receive the following error, there is a possibility that you might be using a different version of Java than the one shipped with MATLAB.
“ERROR: Warning: An error occurred while reading the desktop configuration file”
In order to check the version of Java that MATLAB is using, launch MATLAB and run the following command:
>> version -java
Check for a MATLAB_JAVA environment variable set on your system. If a MATLAB_JAVA environment variable is set, remove it and relaunch MATLAB twice to see if the issue persists.
If this does not help, it is also possible to resolve this via the following commands:
>> restoredefaultpath
>> rehash toolboxcache
>> savepath
I hope this information resolves the issue you are facing.
Thanks,
Keerthana
