You don't even have any Upwork job history on your account.
If you want to, you could delete everything in your profile and start over.
You can't create a new account. Maybe you'll get censured just for posting this question.
If you have another Upwork account, other than this one, then Upwork operatives are probably already looking into it and might take action.
If the account linked to this Community Forum account is your only Upwork account, then you're fine. You have a clean slate. You can do whatever you want.
As Preston noted already, users can have only one freelancer account. Creating duplicate accounts will result in suspension. You can use this account to send proposals and work on Upwork.
