Recover LinkedIn account

I am looking for help recovering my LinkedIn account. I was unable to regain access through usual means; my issue falls under ‘other’ in the sense that something unexpected has happened to make it inaccessible. I have attempted the LinkedIn account recovery process, but sadly to no avail. I have also received some error messages or notifications from LinkedIn concerning my account, which has made it more difficult to recover my account. I am now seeking professional assistance to recover my account.
