Acrobat Crashing / Google Drive Sync Issue

I am having two issues that may be related.  I am on a Mac, current OS and Acrobat DC Pro up to date as well.  I am having frequent app crashes.  Also, some files will not sync through google drive for desktop.  The simply try to sync but they never finish.  If I open some files (and I do not edit or save them, only view) causes my mac to see the file as being modified, and a sync starts that wont finish.  I suspect it has something to do with my fonts - I say this becuase I get errors about some fonts not being available (even thought they are in my font book).  Its becoming a problem for using acrobat, but also for syncing my files.  Has anyone seen this, any ideas on how to fix.  Having been using these tools for a long time, this is new.  And coincided with intalling some fonts in my font book.   Thanks.
