Cannot claim my account for multiversus

The pictures above show the problem I’m having of trying to claim my personal account (DiLyan) But whenever I try it basically claims that someone else has already claimed the account even though I have scrubbed any other linking of any other profiles from this account off the Internet I have uninstalled and re-linked nothing works it just tells me that in place of the claim account option that I can visit the Twitch account that I already linked earlier
