You do not have any debugging symbols required to display the callstack for this crash.

After investigating this issue, it appears to be related to UE-17513. See the accepted answer on the post linked below for more information about how to go about resolving this issue:

Have a great day

Hi Sean,

i updated the installed the newest displayport driver - but the crash still happens.

i send i new crash log.

version 4.11.2 runs well btw.

hope you can help


here you are - hope this is the information you are looking for…

Please provide your dxdiag so I can take a look at your hardware setup to see if there are any potential conflicts.

Take a look at the software conflicts wiki and let me know if you see anything on there that you are using that could be causing this issue: A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

i have 2 graphics cards in the system

NVIDIA Quadro K4200
GeForce GTX 980 Ti

The Quadro is set to do Graphics rendering only and the GeForce GPU does the Rendering. (Setting in the Nvidia Settings) - but even if i disable this setting i.e. the Quadro does both rendering and Graphics UE behaves the same.

Is this concidered a Optimus configuration too or is this only with a Tesla card??

i checked the software list but there is no software i#m using listed


After the crash occurs, could you please provide the log from your project’s Saved->Logs folder? You can attach the text file to a comment.

Since i can not start the engine at all, i am not sure which project folder you mean.

but there is a link at the top of the crash report window which contains log files from windows - is this helpful?link text


I have entered a bug report for the developers to investigate based on your information, UE-33236. Thank you for your report.

One suggestion I have is that if you are using an Oculus, please try running the editor with it unplugged. If this resolves the crash, please let me know.

Have a great day

Hi Sean,

i found a solution - not ideal - but it could help the developers to track down the bug.

i configured the nvidia driver to use only one GPU is active. This can be either the K4200 or the GeForce but NOT both.

then the Engine boots and works fine…

but i’d prefer of cause if i could use the full power of my system…
