Migrated account no longer shows game is purchased

I bought Minecraft in 2010. I recently migrated my Mojang account to a Microsoft account, and I am no longer able to play Minecraft Java (or Window). The only option I get when I open the launcher is to "Play Demo." I should still have access to play Minecraft Java and from what I understand I should also have access to Minecraft Windows - which says "Play Trial." If I go to the Microsoft Store or Xbox App, it says I have to pay for these games - which I already have.
