When launching Sims 4, the EA app says that the game does not belong to me.

Recently, I ran into such a problem that when installing the Sims, I happily ran to turn it on and wanted to play already. I signed up for EA, I think I'll play everything already. As soon as I log back in, it immediately gives out that the game allegedly "does not belong to me or needs to be changed to a user." I do not know what to do, there are no guides about this...I downloaded from steam from the official website. This is not a pirate, do you understand? I bought it legally and the site gives me such game. If there is anyone who knows what to do, I will be grateful if you do a lot.
