Cannot add domain - "Another project is already using this domain" after deleting project

Hello, I deleted a project that was using the domain chimiitdsolucoes.com.br without removing the domain first. Now I cannot add it to my new project because it says “another project is already using this domain”. The old project no longer exists.

Please release the domain so I can use it.

Domain: chimiitdsolucoes.com.br
Project: animated-cheesecake-81927a
