Since you’re getting a Windows crash that is closing the editor and not seeing the crash reporter coming up I’ll need you to follow the instructions on this page and get me the error log that is generated.

- Is this crash happening every time or just that one time?

Additional information I’ll need:

- A copy of your DxDiag as a text file attached.
- Have you tried re-installing the editor or verifying the installation?

I’ve not seen the engine directory issue before so if the above doesn’t lead to anything we can investigate that one a little bit more.

Let me know.
