How do I log back into the Minecraft Microsoft account linked to my PlayStation if I do not...

I have this same error.

Except to my knowledge I have never linked my Microsoft account and PSN before trying to do so today. I only recently linked my Java edition minecraft to my Microsoft account, and today thought I'd try the Playstation version of the game. When I log into my microsoft account it says it is already connected to a different account.

How can I find out which Microsoft account has been linked to my PSN?

I got a problem where i cannot login to my Microsoft account on my ps4 even though i am already logged on to playstation network since the update on december 10th 2019. I was looking up on how to fix it but i didnt see anything to do with fixing this problem.
The problem is basically i cant automatically login and my microsoft account is linked to playstation network. And sorry if it set on xbox even though its about minecraft and playstation.

I am attempting to connect my microsoft account with my Ps4 account. My microsoft account is already connected to a Ps4 minecraft account. How do I find what Minecraft account is using my microsoft account and to disconnect it from it.

Even if you could disconnect it you wont be able to link a different Microsoft account.

Per https://help.minecraft.net/hc/en-us/articles/360037725571-Minecraft-for-PlayStation-4-FAQ

Note: Once a Microsoft account has been linked to a PlayStation® account, neither the Microsoft account nor the PlayStation™ Network account can be associated with a different account. 

If you choose to unlink accounts, then purchases will be returned to the account which made the purchase. Even after unlinking, Microsoft and PlayStation® accounts can only be re-linked to the original account.

Note: As of March 15, 2023, please DO NOT unlink your MSA from your PlayStation account via the in-game menu. You will be unable to link it back if you do so.

This is a restriction imposed by Sony.

Hello, I hope you are well.

Please try these steps.

If the error in Minecraft on PlayStation indicates that there is a connected account and you do not remember the information, it means that the account is linked to your PlayStation Network account. To solve this, you need to unlink the Microsoft account from the game and then try to link it again.

How to unlink and relink:

1. Unlink:

Access the Minecraft settings menu on PlayStation.

Look for the option "Unlink Microsoft account" or something similar.

Follow the instructions to remove the linked account.

2. Relink:

When trying to log in to Minecraft, select the option "Sign in with Microsoft account".

Access the code redemption website on your computer or smartphone.

Enter the code that the game is displaying and log in with the Microsoft account you want to link.

If you cannot remember the email address of the Microsoft account:

Check if there is any account information saved in your browser or device.

If you can't find it, try using Microsoft's account recovery service (if the account was used for your PlayStation account, the email address must be registered

Hi Josef, I’m having the same issue however this is the first time I’ve got minecraft on any PlayStation, I’ve tried logging in to Minecraft on PS5 and it gives me the same message, there is only my account on my PS5 yet it says my Microsoft account is already linked to another PSN account, I do not have minecraft on PS4. I attempted to use a different Microsoft account but all I got was a signing in screen for 10 minutes so gave up.

(Edit: just installed minecraft on my ps4 with the same PSN account and also says the Microsoft account is linked to a different PSN account but Nintendo switch works fine so seems to be an issue with PlayStation minecraft)
