@Youngin Kim,

From your command, it seems that you are running a script that calls the FDTD GUI/CAD.  Please check with IT or the person who created the script/executable "lumerical fdtd-solutions" to check what is called by this script/executable. 

Typically we run the CAD (using the default install path for 2022 R1.1) 


or in your case try opening the FDTD CAD?GUI directly from terminal. Do not use "lumerical fdtd-solutions"  


From your screenshot it shows "Segmentation fault error" -- there is something wrong with your installation. It's could be missing system or graphics libraries needed by the CAD/GUI see this Knowledge Base (KB) for details.
