MATLAB is not creating GUI

Hi,

I am new to MATLAB and have started learning about it quite recently. I tried to create GUI using GUIDE, but an error keeps popping up on the command window. I tried finding a solution for it online, but couldn't find any fitting answer. Here is what the error looks like, and any help will be appreciated :

Error using com.mathworks.toolbox.matlab.guide.template.QuickStartPanel/getPreferredSize

Which operating system are you using, and which version of MATLAB?
