How do I disconnect my Microsoft account from Ps4 from my Microsoft account settings?

I want to disconnect my Microsoft account from my PSN account but Minecraft on PS4 says its permanent, is there a fix for that?

I just bought Minecraft on my ps4 account and when I went to log in, it said that my Microsoft account is already connected to a PSN account. How do i unlink a Psn account from my Microsoft account

Yes

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.

Like I said, if I try to connect with my other Microsoft account it just sits there waiting for connection forever and doesn't actually do anything. Long story short my PS4 cannot sign into any Microsoft account at all.

I appreciate the update and I apologize for the trouble but for cases like this it is handled by the game support which is Mojang, TravisPenner.
