Ionic CLI 6.x [INFO] Waiting for connectivity with vue-cli-service... and 100% CPU

I'm using ionic 6 in a new Vue 3 project and when I run npx ionic serve it runs the build and serves the project correctly (also correctly rebuilds when files are changes). But it logs this info message and is running a processor at 100% apparently in a spin lock.

> npx ionic serve                                                                                                                                      main [⇡]
