I have a problem with my Minecraft account on Playstation 5

I try to log in with my Minecraft account on my ps5 console ... However, it does not let me, I get a message of "UPS seems that this account is already connected" and it recommends me to log in with a previous account ... but I I don't want the old account.

How can I solve that? I have tried everything and there is nothing to help me start my new Minecraft account
