To help resolve this issue, try cleaning the AirPods Pro case:

How to clean your AirPods, AirPods Pro, AirPods Max, and EarPods - Apple Support

Clean the case of your AirPods or AirPods Pro

Clean the charging case with a soft, dry, lint-free cloth. If necessary, you can slightly dampen the cloth with isopropyl alcohol. Allow the charging case to dry. Make sure not to get any liquid in the charging ports. Here are a few more guidelines:

• Remove any debris from the Lightning connector with a clean, dry, soft-bristled brush.

• Don't use abrasive materials to clean the charging case.

•To avoid damaging the metal contacts, don't put anything in the charging ports.
