Crashing in Reader DC when saving and closing

We've been having issues with an install of Reader DC on a Server 2012 R2 machine. Acrobat Reader only crashes when a PDF is saved to any location on the machine and then closed. 

The crash log is below:

Faulting application name: AcroRd32.exe, version: 20.6.20042.43423, time stamp: 0x5e616a22

What I've done:

- Uninstalled/Cleaned/Reinstalled

- Repaired Installation

- Disabled Protected Mode

- Added the bProtectedMode registry key

- Tried in safe mode

- Run Windows Updates

- Made a new user profile

- Tried a different version of Reader (tried Server 2012 version, same result)

- Run SFC /scannow under elevated command prompt, comes back clean

- Used Procmon to watch and record when it faults. Getting a major buffer overflow when it closes. I can attach the procmon log if requested. 

Any thoughts?
