Preheat the oven to 350°F. Mix the graham cracker crumbs, brown sugar, cinnamon, salt, and melted butter, then press the mixture firmly into a 10-inch springform pan. Bake for 10 minutes and cool slightly.
Reduce the oven to 325°F. Beat the softened cream cheese, mascarpone, and granulated sugar until smooth, then mix in the eggs one at a time on low speed.
Mix in the sour cream, heavy cream, vanilla bean paste, and salt just until the filling is uniform. Pour it over the crust.
Set the wrapped springform pan in a water bath and bake at 325°F for about 90 minutes, until the edges are set and the center still moves slightly.
Turn off the oven and let the cheesecake cool inside for 1 hour. Remove it, cool to room temperature, then refrigerate for 6 to 8 hours or overnight before slicing.
