Hello, In order to fix this, you'll need to find the Microsoft account that you used the first time on Minecraft for PS4, it does not matter if you create a new Microsoft account because is the PS4 account the one that's linked to a specific Microsoft
account. If you don't remember which Microsoft account you used, you can go to Mojang support for them to check what's the Microsoft account that's linked to your PS4 account for Minecraft.

Still cant sign in to my mircosoft account on my ps4 for minecraft
