Prepare the slow cooker by coating it lightly with cooking spray.
Place the chicken breasts in the slow cooker and season with salt and pepper.
Add the pinto beans, black beans, onion, corn, diced tomatoes with green chilis, and tomato sauce.
Stir in the ranch seasoning mix, chili powder, and cumin.
Scatter the cubed cream cheese over the top and sprinkle in half of the cooked bacon.
Pour the chicken broth over the mixture, cover, and cook on low for 6–7 hours or high for 3–4 hours until the chicken is fully cooked and tender.
Remove the chicken from the slow cooker, shred it with two forks, and set aside.
Whisk the softened cream cheese into the broth until smooth and creamy.
Return the shredded chicken to the pot along with the remaining bacon and cheddar cheese, stirring until melted and combined.
Garnish with fresh parsley before serving.
