Maximum recursion limit of 500 reached. in Simulink

Hello. I have this problem when I open my project. I am building an electrical grid with Simulink/Simscape, so I don´t have any code that I could optimate, I have already read post to similar problems but I don´t know how could I fix this error. The network seems to be good connected. Maybe anybody has experience with this problem and can help me. Thank you.
