MacOS High Sierra version 10.13.6 crashes on start up without cause

Spent three hours trying to reach Adobe for "in person" support.  I had performed all trouble shooting (uninstall, clean fragments, remove library components), finally got an automatic bot to respond to my query on FB messenger.  Although I had performed all the recommended trouble shooting, I repeated all the procedures to no avail.  this is a new issue, which started today without any change in updating either the OS or the Adobe products.  The product (Acrobat PRO DC) now will not work at all.  Adobe's customer support is no help to date.  

I have done all the trouble shooting steps here:

In Facebook messenger, the first thing I mentioned was my operating system: 

MacOS High Sierra version 10.13.6  

The creative cloud says all my software is up to date and compatible. 

I would appreciate Adobe's help.  By the way, I posted a review of Adobe's products on social media.  I will be happy to revisit and revise my review if/when the problem is solved.  

In advance, thank you for your assistance.
