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:
Thank You.
