How do I fix my Minecraft account login

I got a problem where i cannot login to my Microsoft account on my ps4 even though i am already logged on to playstation network since the update on december 10th 2019. I was looking up on how to fix it but i didnt see anything to do with fixing this problem.
The problem is basically i cant automatically login and my microsoft account is linked to playstation network. And sorry if it set on xbox even though its about minecraft and playstation.

I downloaded Minecraft from play store and i login and i join server and Minecraft said " sorry we couldn't validate your login " how to fix

If this is a minecraft launcher you have to ask the developer to fix their login issues. It's how their software is doing authentication that is causing the failure

I have found a fix for this for my 2 kids switches. Apparently when you create an account with microsoft and use it to log into minecraft it creates an xbox account for you and assigns a auto generated username. All i had to do wasgo to xbox website on
my comp and login using the microsoft login info. Once it logged into the account i went under settings and changed the gamer tag.

The new local account, when I downloaded minecraft onto it, ran everything just fine, no account login. It did not fix the issue on my main profile though.
