Why can I log into Microsoft on my Playstation account

Unfortunately, after trying mojang I get the exact same automated email explaining a few ways to fix it with it saying that it cannot be unlinked as the main.

"If you are unable to find or login to the correct Microsoft account, please contact Microsoft Support here for further assistance, as we do not have access to their account management systems" this is the only real helpful thing but basically just redirects me back to Microsoft and back to square one.

Hi there Elliott welcome to the community forum! Christopher here, an Xbox fan just like you and has been on Xbox for years already. I would really love to make your day by helping you out. Fellow PS user with a similar situation, the bad thing here is that only Sony or Mojang can unlink or link accounts, what is my best advice? To go with Mojang, Sony's support is extremely slow and they can take up to a week to answer back, so give Mojang a go!

Thanks for replying I will give that a go now and hope it works out🙏

Wow, contacting Sony would be the second option here!

I play Minecraft on my PlayStation 4 so that's the console I'm having issues on. I'm not really sure what you mean by third party account as Microsoft only lets you link things to Microsoft approved/partnered things, but it was my Xbox/Microsoft account, I changed the Xbox account's randomly generated username to a new one and that's when I first started getting problems logging into my Microsoft account on the PlayStation but it still let me log back in eventually, then I changed my Xbox username to match my PSN username and now it doesn't let me log in at all.
