Struct contents reference from a non-struct array object in simulink

Hello, I have simple simulink circuit like this

when I run the simulation this error appears

I tried to search about this meesage but I didn't find anything related to simulink so can anyone help me please

it is worthwhile to note that I have tried different circuit that works fine with my friend computer and gives me same error so I think it is local problem but I can't figure which options to check.
