I have a simple project which doesn’t seem to want to cook properly. Maybe someone can give me a pointer in the right direction. Thanks in advancelink text ---

Hi nome\_unreal, This log indicates a crash while packaging. I looked up your full callstack in the crash reporter and it appears to exit due to a D3D11 error. Can you send me your dxdiag? ---

Well, that is definitely not a potato computer. Can you install debugging symbols (from options in the launcher) and re-cook. It’ll give a full callstack instead of the nothing callstack that you have now. ---

Hi , yeah we don’t do well with potatoes. 😉 I installed the debugging symbols and here is the callstack: Callstack I hope this gives you the right informations. Thanks again! ---

Hey , thanks for your continuos support! We have managed to package the game, after removing a Blueprint from the Level and spawning it on begin play. The game didn’t cook with this asset inside of the level. We don’t know why. We did find this work around, but it would be nice to know why this happened in the first place. Here is our project: [Download](https://we.tl/Ho0AKbjGAf) The asset in question is called “MediaPlayerBlueprint” ---

Hey nome\_unreal, Again, apologies for the delayed response time. We have been very busy over the past month and have had some delayed response times as a result. If you could send that file again, it’d be much appreciated. ---
