Unable to Access My WhatsApp Account After Reinstallation

I decided to delete my WhatsApp account for a while, but when I attempted to log back in using my reactivated number, I encountered an error message stating, "You must have the official WhatsApp app in order to log in." Even after trying the official WhatsApp app and resetting my phone, the problem still persists. Interestingly, I am able to access my account using a different phone number. Any help you can offer to resolve this problem would be greatly appreciated.
