Slitherine

I'm playing the latest version. I was able to play the game and complete several scenarios. Now when I try to play, I cannot get past even the first turn in any scenario, without the game crashing with the following error message: An Unreal process has crashed: UE4-UEBA. I am not the first player to see this crash. But I have found no valid solutions listed on Steam. Steam passes the buck to Slitherine to troubleshoot. Will I get any help here?
