Minecraft ps4 microsoft account error?

I can't sign into minecraft ps4 with my microsoft account. When I try it says that on the ps4 screen

I did too, nothing has happened since… It's probably a bad bug

You have already signed in to another PS4 account with the Microsoft account, that's obvious because it is there after all

But I have created several accounts, but each one says the same

Multiple PS4 accounts? Because in that case it is of no use. The Microsoft account is tied to a single PS4 account, you can't change anything. You have to use a different Microsoft account.

I mean multiple Microsoft accounts

But it can also be that you have already signed in with a Microsoft account on the PS4 account and this Microsoft account is now linked to the PS4 account. In that case, there's no point in creating multiple accounts✌

Apparently you've already signed up with someone else at some point; you have to sign in with that and then sign out
