Windows Defender error - Invaild pointer

Windows Defender Version: 1.1.1051.0

I have ran into a problem when scanning my computer which I never had in the
past. When I open Windows Defender it says "You haven't scanned your
computer in 5 days." When I click the "Scan" button, the follow error
appears:

"Windows Defender encountered an error: 0x80004003. Invalid pointer"

This error only occurs when I do a full scan. This error doesn't occur if I
do a quick scan. You can click "Scan" at the top of the main page of the
program and choose "Quick Scan" to do the scan. Then you can do a Full Scan
and this will fix the problem. I hope this helps somebody else.

This is a bug. It is known to Microsoft, and on the road to being fixed,
but code including the fix has not yet been distributed. The workaround
should be to scan via the menus--I believe you should even be able to simply
choose a full scan from the menu.
