Closing to desktop with no message

Sly_Snake · August 25, 2022, 1:23pm

When running my compiled build, it starts on the main menu then loads your selected map on a button click. The problem is, perhaps 1 in 4 times at the end of loading it will just close to desktop without any message. It doesn’t matter which map I choose but some make it happen more than others. Reopening and trying again usually makes it work.

With no message I have absolutely no idea how to even begin debugging this. I have already enabled crash reporter tool but it does not trigger. I have checked system loads (cpu, gpu, memory) during loading but none seem to reach any limit. I have checked the log and it seems to just end suddenly with the last line being normal “map loaded in x seconds”. I have checked windows events and nothing useful there.

How do you go about debugging something like this? Thanks!

In your Project Settings search for these two options
Include Debug Files and Include Crash Reporter. I think they are under Packaging section.

Then you will have crash report logs that can help you with your crash.

Crash files location:

Windows: YourGameDirectory/YourGameName/Saved/Logs
Mac OS: Library/Logs/YourGameName/

Thankyou. I think I have found the first clue in one of the crash dumps. It says:

Ensure condition failed: InstanceSceneData.IsValidIndex(RenderInstanceIndex) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\InstancedStaticMesh.cpp] [Line: 1442]

Does anyone have any clue what this might mean?

Ensure is not necessarily a crash. Can you give us full log, so that we can check a bit better?

The same message comes up in the crashdumps when the compiled app crashes. I am now able to make it happen in the editor too (but it doesn’t crash it there), the first time I load a map and press play, it comes up with the following in the output log. Any load after that has no errors.

Foliage parts of the maps essentially got corrupted during a transfer. Thanks for the guidance
