How can I unlink my PlayStation Network account from my Microsoft account settings?

How can I unlink my PlayStation Network account from my Microsoft account settings?

For context:

• What I have access to:
• I have access to the Microsoft account.

I do not have access to the PlayStation account.

• Why I need to do this:'

I am trying to play Minecraft on my PlayStation, however, when I try to log into my Microsoft account, I get the error: "Oops! looks like the Microsoft account you are trying to use is already connected to another account for 'PlayStation Network'."

I do not have access to the PlayStation Network account in question which my Microsoft account is linked to through Minecraft.

This means that in order to unlink the two, I must do it through the Microsoft account

Background I have

I have looked at the Microsoft forum and have found the same question, however an answer (that works) was never given. The only real response was one of a method that seems to not work any more. I'll link that forum here:

In other words, is there any way I can unlink a PlayStation account from my Microsoft account if I only have access to the Microsoft account on Windows or mobile?

I'm trying to avoid making another PlayStation and another Microsoft account, so an answer would be helpful. If there is no solution I am open to alternatives. I also do not want to buy Game pass on my Xbox because I already have PlayStation Plus.
