How do I fix my Gallery and Camera Apps?

[Android Central Question]

I have an Android 6 and I just updated it last night. Everything is working fine, except I notice that my Gallery comes up as a Black screen and closes out after a few minutes and my Camera suddenly doesn't want to take pictures. I am looking for a simple and fast solution, if there is one. Help, please!
