Deleted project's domain is unavailable for use in my new project

A few days ago I had deployed a beta version of a project and removed it, using the domain http://regim.vercel.app/

And now while deploying the final version of the project, im trying to use that domain http://regim.vercel.app/, but it says “This domain regim.vercel.app is already owned by another Vercel account.”

This seems to be a recurring issue that has occurred before to others too, and there doesn’t seem to be a way for me to fix it from my side.

How long ago did this happen? Sometimes it needs a few days to “release” that domain

It was 10 days ago, on April 20th when I had made the old project
