Add the chicken thighs, onion, bell peppers, carrots, garlic, corn, smoked paprika, salt, and black pepper to the slow cooker.
Pour the chicken broth over the ingredients and stir gently to combine.
Cover and cook on low for 6 to 7 hours until the chicken is tender and shreds easily.
In a small bowl, whisk the heavy cream and cornstarch until smooth.
Stir the cream mixture into the stew, then cover and cook on high for 20 to 30 minutes until the broth thickens.
