Minecraft says that I own the game, and when I launch the game it gives me the demo

The minecraft launcher says to me that I own Minecraft, But every time I launch the game, no matter the version, It only gives me the option for the demo. Every time I open the launcher, It logs me out despite having the "keep me logged in" box checked. I figured it was because the current Account migration going on, but when I looked, I wasn't able to migrate it, Even if I wanted to. Do you have a solution?
