Place the chicken breasts in the bottom of the slow cooker. Sprinkle the ranch seasoning, chili powder, cumin, onion powder, garlic powder, and paprika over the chicken.
Add the black beans, corn, and diced tomatoes on top of the chicken.
Cover and cook on low for 5-6 hours or high for 3-4 hours, until the chicken is tender and cooked through.
Use two forks to shred the chicken directly in the slow cooker. Stir everything until well combined.
Add in the cream cheese and cook on high for an additional 30 minutes. Once cream cheese has melted, stir to combine everything.
Serve hot with toppings like shredded cheese, cilantro, or sour cream. Pair with tortilla chips or warm cornbread.
