Hi Mel-24,
We'd like to help guide you in the best direction for a solution. We would recommend starting with making sure the AirPods and the case both are clean and free of any debris, and steps here for How to clean your AirPods, AirPods Pro, AirPods Max, and EarPods will help. Once clean, be sure to have both in and charged. If this remains to be an issue after those steps, unpairing with a reset will be the next best steps and you can find those steps here: How to reset your AirPods and AirPods Pro. With the steps followed, and if you are not met with a solution, you'll want to reach out to Apple Support. You can use the link below, if needed.
