Netlify network error after deploying

Below is my website, which is created by React and was successfully builder and deployed.

I have done settings for _redirect , not to have 404 page error when refreshing.

But I still have network error whenever I refresh the website.

Can anybody solve this network error problem? If it were a CORS error then it should’ve not been showing the page at the first place, isn’t it?

But it only happens when I refresh the page or go back to previous page.

Thank you for your help!
