Android icon shows as app icon

[AC Question]

I have the Moto G5 running Nougat and the default android robot is showing as the App icon instead of the actual app.

Welcome to Android Central! It's showing as the icon for which app? All of them? Is that only on the homescreen, or also in the App Drawer?

The default Android icon usually appears when the app itself is "broken," like if you moved the app to the SD card, and then the SD card either malfunctioned or became Unmounted.
