Why i got That
I've no idea! There isn't enough information in the provided screenshot nor have you provided a context comment of how it crashed in the first place, I need a crash log for more specifics.
You can either provoke the crash again and press on the "(click there to view directory)" and send the crash information or you can go to following folder in your PC and provide me with the latest logs:
c:\Users\YourUser\AppData\Local\Changed3D\Saved\Logs
(there might also be a folder with the name "Crashes", that also works)
