UE4 4.17 crashes upon launch

Hey,

I’m unable to launch the 4.17 build of my project; I do not get any crash reports, just a typical “Unreal Engine can not respond” error - twice, before it shuts down. The editor does not open. The project runs smooth in 4.16. I don’t have any plugins installed. The project is using 400 tiles in world composition, volumetric fog. I’m using Ultra Dynamic Sky, but I doubt that would be the culprit as it has support for 4.17. Anyone else experiencing this?

I’m able to open all other templates, it’s mainly crashing when I try to open my project. Would love some help for this as I was looking forward to using 4.17.

I fixed the issue. The Planar Reflection asset in my scene was crashing the project. Would love if anyone could shed light on why though.
