Is it possible to fix this?

What code and which system?

I have a problem. About a year or so ago i deleted a microsoft account that i don't use, meanwhile i had that account linked to my playstation 4's minecraft. But since i didnt unlink it before i deleted it, it wont let me link another accound because it shows there is still one connected. Is there a solution?

Hey Austin, to be blunt, this doesn't have a direct answer.

The thing is, Minecraft uses an entirely different (and imo, unnecessary) account system compared to other games like Hogwarts that requires you to create a Microsoft account. This isn't Mojang's fault, it's their owner. The thing with creating a Microsoft account for Minecraft is that—the Microsoft account isn't centered towards the game itself. An account link for a game like Hogwarts has Wizarding World. A Wizarding World account is Hogwarts version of a Microsoft account. And a Wizarding World account is centered towards the game itself (and any related content). A Microsoft account isn't. You can see how this will create problems.

To fix this, you will need to contact Minecraft Support. Microsoft Support will not be able to help you because you deleted your account. Neither can Sony since this happened on Xbox servers.

Hopefully this helps.

once you link an account it is permanently linked, even if you unlink it you can only re link it with the same account, this is a psn requirement that once accounts are linked they stay linked forever, you would not be able to link to another account even if you did unlink the other one.

do you honestly think they are not trying? im retty sure htye are not sitting back and are all happy with the problems they are having

This worked for me. Thanks
