Game Loop returns me to Mojang even after migrating my account

My account was migrated. Installation returns me to a Mojang sign in screen which says my account was migrated, sign in with Microsoft. I do that, but cannot access my game anywhere and when I try to re-install my game (now done 3 times), I go through the exact same loop. I simply want to play alone at home as always. I purchased this and wish to play. Can I get back to it?
