Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting Def Ed Engine won't launch

I get an immediate crash error upon starting the Def Ed Engine that says "Glasses has stopped working..." on Steam.

The Classic edition seems to start up just fine, and I was using the Def Ed all last night with no issues. I tried uninstalling the program several times, restarting steam and windows. I even tried to boot up the program directly from install folder under Run as Administrator. It just will not start.

Something drastic has changed since last night and I'm not sure what to do.

Can anyone advise? Running on Windows 7, NVIDIA GTX 980, INTEL i-7 4790k & 16 GB RAM.
