Place the chicken breasts in the bottom of the slow cooker. Add the chicken broth, diced tomatoes, black beans, corn, onion, garlic, cumin, and chili powder.
Cover and cook on low for 6 hours or until the chicken reaches an internal temperature of 165°F.
Remove the chicken and shred it with two forks. Return the shredded chicken to the slow cooker.
Add the cubed cream cheese. Stir until the cream cheese melts fully into the broth.
Taste and add salt and pepper as needed. Serve hot with tortilla strips, shredded cheddar cheese, and chopped cilantro on top.
