Game crashes at launch on MacOS

[darthbator]

Here's a clip of the debug info the OS spits out at application crash. It looks like some manner of code signing issue. I've not kept current on how Apple is doing this stuff these days? Did the certificate this game was compiled with possibly expire? (this is from the steam version of the game)
