Unresponsive DW 19.0.1

All of a sudden, my DW 19.0.1 started becoming "unresponsive".  It will start up, bring up the workspace, and then on my iMac I get the "beach ball".  I waited 30 minutes and zip!    I did an un-install using the Creative Cloud manager and then an "update" (it did now have a re-install option).  No change.  17.5.0 works just fine as does 18.2.  Using latest Mojave 10.14.2.

Tried rebooting, any ideas what to do next?
