Found what is causing this problem...

The version of yarn...

I have v1.17.0 on a different computer and it works, but with the latest yarn v1.17.3 it doesn't

Mauros-MacBook-Pro:website maurodelazeri$ yarn start --host 127.0.0.1 --port 3007
yarn run v1.17.0
warning package.json: No license field

I trying with npm in 6.10.3 version and this problem continue with the release 1.12. However with release 1.11.1 (Docusaurus) it works.

The only change between 1.11.x and 1.12.x is the version of portfinder package. No other code seems to touch the port code :o

seems like dep bug

I am unable to reproduce this with [email protected] and [email protected]. According to the linked issues, this bug appears to have been reverted upstream.
