Link Fortnite Account? - 2

I have the following problem:

I've always played Fortnite on the Switch before, but now I've got a ps4 and play on it with the same account, but wanted to offer lobbies, so I separated my epic account from the Switch account and played on the Switch without an Epic account. Now I would like to link my epic account with the switch account again, but that is no longer possible I've already tried everything! Therefore my question: can I somehow delete the game status of Fortnite on the switch so that I'm back to the beginning that I can link my epic acc again?

You have to talk to your switch so it worked for my friend

Is it enough if I reinstall Fortnite?
