InCopy CC 2015 Crashes at Initialization

Hello,

I am having an issue with the Creative Cloud 2015 versions of InDesign and InCopy.  Recently, both of those programs started to crash right after Initialization.  I receive a crash report each time.  However, this is not occurring for all users.  This is occurring on MacBook Air Early 2015 models.  They are running MacOS 10.10.5, hence why I we are running the 2015 versions of CC programs.  It is only affecting these two programs and only for most non-admin users(i.e. Students).  This was reported to me about 2 weeks ago.  No system or program updates would have been ran just prior to that.

Here is the crash report: Process: Adobe InCopy CC 2015 [456] Path: /Appli - Pastebin.com

Steps I have attempted thus far:

-Wiping out user preferences via keyboard command at startup

-Reinstalling programs

-Repairing Disk Permissions via Disk Utility

-Temporarily granting read and write permissions to affected user account for program

Are there any other steps to try?
