To fix the issue if you are on a Windows,

go to bottom left side of computer screen on Windows where it says type here to search
type in UPDATE
next a screen will come up,
click check for updates system settings,
then under the grey box CHECK FOR UPDATES,
if you SEE FEATURE UPDATES download and install??
download and install all of them, especially the Feature updates

now sometimes it
takes a while to download
it will go from 0 to 100% 2 times,
make sure to close out all
windows but this one
and when it says PENDING RESTART on THIS page
you click that button.
After this there will be no more issues.

If on a MAC you will also need to update your Mac, 

From the Apple menu  in the corner of your screen, choose System Settings. In the window that opens, click General in the sidebar, then click Software Update on the right. (In earlier versions of macOS, choose Apple menu  > System Preferences instead, then click Software Update.)
