Hello Toni,

Manjaro Linux does not seem to be a supported Linux Distribution (Linux System Requirements - MATLAB & Simulink (mathworks.com)). There are many reasons why this exception would occur, many of them will have to do with libraries that may not be available on the Linux Distribution.

Try to set aside the libfreetype.so.6 in “<matlab_root/bin/glnxa64>” using the below commands:

cd <matlab_root>/bin/glnxa64/
mv libfreetype.so.6 libfreetype.so.6.old

I have attached a few links for a reference/workaround:

• Why will MATLAB not start up properly on my Linux machine? - MATLAB Answers - MATLAB Central (mathworks.com)
• Why is MATLAB unable to run the MATLABWindow application on Linux? - MATLAB Answers - MATLAB Central (mathworks.cn)

Thank You.
