i've also tried reinstalling my node js. currently it's on version v10.14.0. i have also tried deleting and reinstalling create-react-package but to no avail.

i'm quite confused with this error as i'm not well adept yet with npm, so any advice would greatly help. thank you!

Do you want to check if you are logged into npm using npm whoami?

I just ran that and noticed I was logged out. Logging back in fixed the issue. Before I logged into, I could download all packages without the scope namespaces ie I couldn't download @babel/pkg-name, @expo/pkg-name etc.
