What to do if browsers see the project on one PC, but not on the other PC?

Question

Google Chrome

I deploy the project, on one PC the project is working, on the other there is no exactly the same configuration (on both PCs I started everything myself). Gives such an error, tried to fix it and wrote headers, everything is meaningless, he does not see

On the other PC, the structure is displayed and everything works.
Project without backing, classic react-typescript.
