Domain already assigned after deleting hosting account

Hi, I am facing an issue with my domain sudarshaninn.com. Earlier, I added this domain to my InfinityFree hosting account, but due to some issues, I deleted that hosting account. After that, I created a new hosting account and updated my domain nameservers in GoDaddy to: ns1.infinityfree.com ns2.infinityfree.com Now when I try to add the domain in the new account, I get the error: “Domain is already assigned and in use.” It seems the domain is still linked to my old deleted account. Please release/unassign this domain from the old account so I can add it to my new hosting account. Thank you.
