I am building a cross-platform app that requires Google sign in. So far it works on Android, iOS and Mac, but on Windows, I keep getting this error

TypeScript
Unexpected error signing in with OAuthInvalid argument(s): Callback url scheme must start with http://localhost:{port}
TL;DR
Developers experiencing an issue with Google OAuth on Windows, the error indicates that the callback URL scheme must start with http://localhost:{port}. Ensure the callback URL is configured correctly for Windows compatibility.
