Access allowed to camera for apps

What about looking in here:

Settings, >Privacy & Security, >Camera

Then scroll to those two apps and see if the slider is green

Another thing that you might check...

Do these apps have access to your photo gallery?

Settings, >Privacy & Security, >Photos

I hope that this helps you

Uninstall the apps and re-install them. When you first launch them, you should be asked if you want to allow them to access locations again.
