Heat oven to 425°F and spray a large rimmed sheet pan.
Brown beef 7-8 minutes, drain, and stir in chili powder, cumin, salt, rinsed beans and corn.
Lay 6 tortillas around the pan so they overlap and hang over the edges, then place 1 in the center. Sprinkle half the cheese, add the beef mixture, then the remaining cheese.
Fold the overhanging tortillas over the filling and top with the last tortilla to cover any gap. Spray the top, then set another sheet pan on top to press it flat.
Bake 20 minutes (remove top pan for the last 5) until crisp and golden. Cut into squares and serve with salsa and sour cream.
