As per the directions - having contacted customer support and running the MacFont test tool without correcting the issue - I am now posting that I am experiencing a hang on the opening of Logos on Mac.
As an aside, this customer service experience has been a bummer. Not sure how I will proceed as far as Faithlife products are concerned.
Attached are my logs.
