unlink Microsoft from playstation

Hi,

Try unlinking your Microsoft account from PlayStation (if possible because I don't use it). you can also unlink 3rd party apps/sites (such as PlayStation) from your Microsoft account from here:

Hey amirhossein, sorry you're having trouble! I'm here to help clarify.

The only way to remove or unlink a Microsoft account from your PlayStation is by going into your PlayStation account settings. Microsoft does not control the linking on the PlayStation side, so you cannot remove it from your Microsoft account directly. You may need to contact PlayStation Support to help unlink the Microsoft account from your PSN account.

I hope this helps you! Let me know if you have any other questions.

I need to unlink my PlayStation Network account from my old Microsoft account which I don’t remember, & link it to a new Microsoft account to play Minecraft

You can unlink the psn account however you CANT link a different one.

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.

This is coming right from the Minecraft website

It is not possible to unlink a PlayStation account from a Microsoft account. Once it's done it's done and you can't link another one

That's really weird, since when you unlink a Minecraft/Microsoft account from a Playstation ID it can only be linked to the same Playstation ID.

Are you completely sure you are signed in with the correct Playstation ID and trying to login with the correct Minecraft/Microsoft Account?
