Combine the flour, yeast, and salt in a large bowl. Add the walnuts and cranberries. Mix well.
Add the orange juice, water, and maple syrup to a small saucepan. Heat on low for a few minutes until the mixture is warm to the touch (about 95 F/35 C). Do not simmer or boil it.
Slowly add the wet ingredients to the flour mixture. Stir to combine until all the flour is moist. It will be a shaggy, sticky dough at this point.
Cover the bowl with plastic wrap and let the dough rise at room temperature for 12-18 hours.
Cut a piece of parchment paper that will fit into your Dutch oven or oven-proof pot with a lid. It should extend over the sides. Set aside.
Turn the dough onto a lightly floured work surface, and, using lightly floured hands, form a ball with the dough. Place the dough in the center of the parchment paper and add it to a clean bowl. Cover with the same plastic wrap or a tea towel, and let it rise for 30 minutes.
Place the empty Dutch oven with the lid on it into the oven. Preheat the oven to 475 F (246 C).
Carefully remove the Dutch oven. Lower the parchment paper with the dough and put it into the Dutch oven. Add the lid and trim any excess parchment paper.
Add the Dutch oven (lid on) in the center of the oven and bake for 25 minutes.
Lower the heat to 400 F (200 C), remove the lid, and continue baking the bread for 5-10 minutes until the top is brown and the bread is crusty and firm. Test for doneness by tapping the top of the bread. It should sound 'hollow'. If you check with an instant-read thermometer, the center should be about 190 F/90 C.
Transfer the bread to a wire rack and cool for 20 minutes before slicing.
