DFGI is currently not a supported feature.
I was able to open the level once and after a few seconds of being opened the editor crashed while compiling shaders and generating mesh distance fields.
Since then I have not been able to open the level at all before it crashes.
This was reproduced on a R9 390X.
This crash also reproduces in a default scene if you enable Ray Traced Distance Field Shadows in a directional light and PIE.
Expected Result: The level loads up and compiles shaders without error
Actual Result: As the level is compiling shaders and generating mesh distance fields the editor crashes

There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-40449 in the post.
