Impossible to unlink a deleted Microsoft account from Minecraft bedrock PS4

Hi. I had a Microsoft account connected to my PS4 to play Minecraft Bedrock. I ended up fully deleting that account because of gamer tag issues. Now when I try login with my new Microsoft/Xbox account on the PS4 it says that I'm already connected to the old account (the deleted one). But I have no way to unlink the two account as the Microsoft account doesn't exist. I created another Microsoft account using the same email as the deleted one, I tried connecting this one to the PS4 but it wont connect. I tried deleting my Minecraft save data and I still have no luck. Both PlayStation and Xbox support told me to ask Mojang about this problem. How can I unlink my PS4 Minecraft from an account that no longer exists?
