contextmenu64.dll - Explorer crashes when trying to move files/folders from one location to another.

I used ShellExView to display all the shell extensions, hid all the microsoft shells, then looked for the most recent shell addition. I had not had the issue until recently, so I looked for the most recent add-on. I turned the shell off and was immediately able to trnasfer files with no issues. Apparently this file has to do with Google Drive and Adobe Acrobat, but since I don't use Acrobat unless absolutely necessary, I kept the extension turned off.

The details of the shell extension that might cause the problem:

Shell Extension Name:	GDContextMenu Class
Filename:	contextmenu64.dll
Description:	Google Drive shell extension
Company:	Google
Product Name:	Google Drive
File Version:	3.42.9858.3671
CLSID:	{BB02B294-8425-42E5-983F-41A1FA970CD6}
