after npm start i should see my website but instead i see this.

so yesterday i changed the root directory of my project because i was having deployment issues (like a folder(all project files) inside a folder) and i did it by CTRL+X and CTRL+V(asked gpt) and my project was running fine locally even after this but deployment issues were still present. Today however my project is not even running locally. I did not do anything to the code today so how can this happen? Can somebody please help.Is the problem even solvable?

the project github link:

Thank you in advance.
