CorelDraw 2018 Crashes when opening files

As of Monday 11/5/18 CorelDraw is crashing when trying to open files.  I have been using CD2018 since June without issues. Have installed on two devices Laptop and Desktop, Same issue.

Uninstalled and reinstalled and same issue. No error messages, just closes. I have been a User since version 1 of CorelDraw.  Much work already re-created in 2018 so I can't go back. Microsoft did have an up date to Windows 10 last week (10/30) but I have been using the application since then.  Help I have work to get done or I'll be out of business.
