Dependency Conflict on Fresh Install (no pnpm) (ERESOLVE unable to resolve dependency tree)

I ran:

npx create-next-app@latest nextjs-dashboard --example "https://github.com/vercel/next-learn/tree/main/dashboard/starter-example"

(no pnpm)

I got this output:

Creating a new Next.js app in /home/<redacted>/Desktop/nextjs-dashboard.

Downloading files from repo https://github.com/vercel/next-learn/tree/main/dashboard/starter-example. This might take a moment.

Installing packages. This might take a couple of minutes.

Seems weird because wouldn't react@19.0.0-rc-f38c22b244-20240704 be >= 16?
