localhost:1234 404 Page not found potential solution

[SunnyAtTelus]

When the laptop is newer, try install a newer version of node (i.e. node 17) and then clear cache to reinstall everything. My work laptop was newer and I was following step by step but still getting 404 Page not found until I install a newer version of node. My personal laptop was older so it worked fine without the newer version of node.

That's right. Ensured I was on the latest (lts) node version nvm use --lts. Then deleted node_modules, dist and .parcel-cache. Re-ran npm i and npm run dev, 404 went away.
