Microsoft account Minecraft won't connect?

I just wanted to create a new Microsoft account for Minecraft, so I signed out of Minecraft with my old one. I've made infinite accounts, but whenever I want to log into Minecraft, it says that the Microsoft account has already been assigned to another Psn Acc. But that can't be because I only created it a few seconds ago. And on the Microsoft side it says I would be connected.

Something has to pop up in the launcher for it, but I didn't get it myself, I read it on the XBOX page, the official Minecraft page and on the Heise News page.
