Can't open Samsung grand 2 camera

I don't remember what I uninstalled
So I can't use my camera now
It shows 'Fail to launch the camera. Please retry or reboot'.
I don't know what to do.
Please reply me back.
Thanks

First, Power Off and Restart the phone.
If no good, try Settings, Storage, Cached Data, and clear the cache.

Tell us if still no good.
