Seems Like Network Problem

Have you changed something with your network? Like DNS or something? is so please make it to default settings this is network issue it only happen when you have changed some settings or else this https issue can you do one thing?

1. Run this command npm config edit
2. This will open the file in CMD and find the registry it will be something like this registry=https://registry.npmjs.org/
3. If there is https then make it http and if the url for the registry is something like Github then change it to this registry.npmjs.org/.
   Let me know the result.
