Alright, so I bought the game and installed it, after 5-10 minutes I clicked on the "Play" button to run Minecraft Dungeons and as soon as I do i get greeted with a nice little error box saying this (Image attached)

[The path to the launcher]
[Another path]
"The specified user doesn't have a valid profile."

What I tried:
Created an xbox account thinking that it would fix it, but it does not.
Reinstalled the game and see the results. (Nothing too)

There is no .minecraftdungeons folder, just the app from the microsoft store.

I downloaded the launcher from https://www.minecraftdungeons.net/en-us/download/
And apparently it opened, then i logged into my account. i already bought the game and it says "Buy Now"
