Sporadic crash when starting editor


When starting Unreal Editor v4.12.5 it will sometimes crash - occasionally BSOD, or sometimes just disappear completely. Sometimes it will start cleanly.

The project is basically an empty project.

I’ve attached the crashdump and various files.

I should add that its the launcher based editor NOT a built from source editor, also run on Windows 10 Anniversary Edition.

Kind regards

  • Does this happen in every project, or only one particular?
  • Could you provide your dxdiag?
  • Have you ensured to update your graphics drivers to the latest?


This project is basically the default blueprint project with starter content.

I attach the dxdiag.

Interestingly I’ve built the editor from source, and that doesn’t seem to have any problems…

Graphics Drivers are all upto date (as far as I’m aware)

Could you do me a favor and test this in the 4.13 preview to see if you get the same crash occurring?
