Even though it takes a lot longer to make slow cooker pork chops versus cooking the pork chops in the Instant Pot, you can make it either way. Once you place pork chops in the slow cooker, you'll want to cook the meat and apples for 5-6 hours on high.  Add the pork chops and place the lid on, and walk away. I recommended testing the pork with a meat thermometer and making sure that it's done and cooked all the way. If you need to cook the pork longer, you can place the pork chops back into the slow cooker and continue to cook.
