Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this XCHRIS16839

Usually that message appears when you had an account linked to your PSN account.
And right now unlink a Microsoft account from a PSN account is not possible.

Is stated in the link below:
https://help.minecraft.net/hc/en-us/articles/36...

"WARNING Once a Microsoft account has been linked to a PlayStation:registered: account, neither the Microsoft account nor the PlayStation:tm: 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:registered: accounts can only be re-linked to the original account."

If you're more than sure that you're using the correct account / you never linked an account previously
You can reach Mojang support to see if something can be done from their side

The following is found at

Hope it helps!

If you can’t play or use content that you downloaded previously, it may be because you're trying to use content that’s associated with another console and you are not signed into Xbox Live. To fix this problem, try the following solutions.

Solution 1: Use account you used to purchase the content

1. Sign in on your console by using the account you used to purchase the content.
   
2. Try to play or use the content.

Note If you recently transferred content to a new console, you can play the content on your new console if you sign in using the account that originally purchased the content. If you want to use the transferred content without signing into Xbox Live
or with a different account, you’ll need to transfer the content licenses to your new console. For information on how to do this, see

Xbox 360 Digital Rights Management.

Solution 2: Delete and download the content again

If your console was repaired or you used the license transfer tool to transfer licenses from one console to another, the locally stored licenses might be out of date. You must download the content again to update the locally stored licenses. Here’s how:

1. On your console, sign in to Xbox Live using the gamertag that you used when you originally purchased the content.
   
2. Go to Settings, and select System.
3. Select Storage, and then select the location of the item (for example,
   Hard Drive).
4. Select Games & Apps, and then locate the game and select it.
5. Select the item that you’re having a problem with, and then select Delete.
   
6. Return to Xbox Home.
7. Go to Settings, and select Account.
8. Select Download History.
9. Select the item that you are having download problems with, and then select
   Download Again.
