Place the chicken breasts, black beans, corn, diced tomatoes, onion, garlic, cumin, chili powder, smoked paprika, salt, and pepper in the slow cooker.
Pour the chicken broth over the ingredients, stir to combine, and cover.
Cook on low for 6-8 hours or on high for 3-4 hours, until the chicken is cooked through and tender.
Remove the chicken breasts, shred with two forks, and return to the slow cooker.
Stir in the cream cheese and heavy cream until fully melted and combined.
Cook for an additional 15-20 minutes to heat through.
Serve with tortilla strips and optional toppings like shredded cheese, sour cream, and avocado.
