PROBLEMS WITH CONTACTS> NO SOLUTION ON THE INTERNET

Hello,

I have been searching in the internet for possible solutions for my issue, but there wasn't any, which made me freak out a lot.

Yesterday I opened Whatsapp and it crashed and closed. I reopened it a few times but the same thing happened. When I opened it again after a few seconds, every single one of my contacts showed up as numbers instead of names.

I opened the Phone app and there weren't any contacts as names there too, there wasn't even the contacts option in the bar at the bottom as you can see.

Then, I dialed a friend's number and clicked on "Add Contact", but the Phone app immediately crashed. I repeated the same thing, but it crashed every time.

So, I thought if I couldn't add contacts by the Phone app, I could add them from Whatsapp. I opened it, opened a chat, clicked on my friend's profile and clicked "Create New Contact", but it said that Whatsapp didn't have access to my contacts. I opened Settings> Whatsapp, but the Contacts option wasn't even there. (I also can't send photos and can't use the camera because those options aren't there too.)

The first idea I had was to restart my phone but there wasn't a Restart button there. I've never experienced all of this before.

I thought I could delete and reinstall Whatsapp, but I haven't backed up my chats and I didn't want to lose them. So I installed Viber and logged into my old account. Same problem with it, too, Contacts, Camera and Photos don't show up in its settings, too.

So, the last thing I tried to do was: I opened Settings> Privacy> Contacts, to see which of my apps needed to have access my contacts, and then turn the option on, but no app was there, while I have Whatsapp and Viber installed.

Then I opened the Contacts app and every contact was there, which is a good thing that I didn't lose my contacts, but also very confusing.

At first I thought it was a storage problem, because my iCloud storage is completely full and my iPhone storage is almost full, but I don't really think so right now. I haven't had issues with my phone before so this is very strange, because there was no solution on the internet, too. I really need my contacts and Whatsapp, because online school is starting soon.

Any help would be appreciated,

Mishel.
