Unable to link Steam account

The linked account is not associated with my Steam account; I must have unlinked it a long time ago.
Now I have pre-ordered Battlefield 6 on another Steam account.
When I select to link Steam, the system prompts:
“Unable to link your account because the EA account associated with *****@outlook.com is already linked to the Steam account associated with xxxxxx. Each EA account can only be linked to one Steam account during its lifetime.”

Please help me resolve this issue.
