Hello @XH !
From what I can see from the attached screenshot, it seems that the model you are trying to build is placed at a wrong path (C:\Users).
It is very likely that you(or MATLAB) do(does) not have the correct privileges/write access in C:\Users. Please try to move the model at the path where your MATLAB projects are stored and re-build from there. Or if you did not make any changes to the model, you can try to build it directly from the Examples folder of the toolbox.
Best regards,
Florin.
