Have come across a couple problems with the login process, and once with a file. To start, i bought the game off of it's respective site, Mojang, I downloaded the launcher from there, and since, have received a login error message, one of the images shows the error in the top right corner. Next, Microsoft store told me i could install the game because i had ownership, loaded in after the 3GB install to get ownership error, which i know others are experiencing currently, but also an error code, which caused my game to stop working and would refuse to start with a popup, which is also something experienced by someone else. there's a screenshot of it here.
