Adobe X Pro crashing every time after sending a PDF attached Email

This is a VERY strange issue.

Adobe X Pro

Whenever I attach a PDF to an email using EITHER the app's attach to email function, OR directly in the email, Adobe crashes. The emails seem to be going out fine, and this does not impact functionality of Adobe after clicking "close" on the crash dialog, but I get the crash notice every. single. time. If it's relevant at all, I use Outlook 2016.

Here is the error signature:

What I've tried:

1. I've tried repairing Adobe

2. I've tried uninstalling and resinstalling Adobe

3. I've tried creating the folders ToolsSearchCacheRdr and ToolsSearchCacheAcro in the appropriate AppData directory

4. I've tried disabling Windows preview pane and Adobe Share Pane

5. I've tried setting process priority to high for Adobe

6. I've tried turning off DEP for Adobe (does not work)

I've really done some legwork here and I can't seem to fix it. Please advise.

Thanks,
