If your card isn’t corrected before your current EAD expires, you have option to re-apply for EAD again and get automatic extension for existing EAD for 540 days and continue working.
Did you receive the new EAD card from USCIS? I am facing the same issue. They approved my EAD till July 2022 when I already have my old card till July 2022. The new H1B is approved till 2025. I sent the card back after raising a service request, has been over 2 weeks not heard anything back.
