Contacts have disappeared, but still on phone
So, I am having a weird issue where all of my contacts have disappeared out of the Contacts app (and phone app) on my iPhone 7 (iOS 13.4.1), but I can tell that the contacts are still on my phone's memory somewhere because if I go to Messages, I can type in their name in the "to:" box and they will pop up as normal with name and number. If I go to the Contacts app, it says "No contacts". All incoming calls and messages I receive show up as unknown numbers. If I ask Siri to call a contact, let's say Deborah for example, she will say "Sorry, I don't see Deborah in your contacts". Yet, I can go to Messages, type in her name, and the name and number show up as normal.
