Related to Domain Management

I accidentally deleted my Netlify project while my custom domain was still pending DNS verification. Now I created a new project in the same account, but when I try to add the same domain it says “Domain is already in use.” The old project no longer exists. Please release the domain association so I can assign it to my new project. my project need (ravclean.com.au) but is mistakenly type the domain in another project and it was in dns pending process.i deleted that file .now in new project when i enter the same domain it says it is already use in the another project.
