Fail to start project studio

[Mattylam]

I am currently following the tutorial on langgraph, however, I cannot open my langgraph studio. I did some research it seems that the error has something to do with self deployment and connection withLanggraph cloud. I am just looking to learn about langgraph studio at this stage, I will start working at a company that will give me the paid version. This is the error I am looking at. Hopefully, someone can give me some advice. All I want to do is follow the tutorial and open the studio successfully. It worked a few days ago.
