OSX Crashing on New Brawl Deck Creation

When I click “Create Deck” the app crashes. I think I’ve used Apple’s reporting tools to send the report, but this happens 100% of the time now. (It worked to build the first deck, but after deleting it, it now crashes every time.)

This is on a MBP 10.14.3. What more do you need to address this repeatable crash?
