UE4: Crash on level load

Development Platform & Builds

Hello, I have a problem with my software under unreal Engine and I don’t know how to debug it.

I have a very big map with persistent level data.
I I load it in the engine it works fine.

If I load it from a MainMenu level it crashes the editor.
If I load another level from the same MainMenu it works.

How can I debug this ?
I was working in a previous version of the level.

Additional info: it only crashes in the editor.
It’s OK with a WindowsNoEditor version.

Hello,

  • Could you provide the logs from your project’s Saved->Logs folder?
  • Could you please cause the crash again and provide your Machine ID and ensure that you hit send on the crash report?

Sorry but the files are very big (more than 21 GB !!!)
I can’t open it with an editor and now I’m unable to open my project.

It crashed while I pushed the play button. Since that I can’t open it any more and I’m afraid I’ve lost all I’ve done on the FirstPersonCharacter tonight…

Bad waves !
I’m going to rest, and will try again tomorrow (maybe I should delete all temp and saved files)…

I forgot to mention that in both case I did not have the crash Windows.
First case: the editor closed without crash window.
Second case: I had to kill the editor because it hang up.
I really find 4…1 preview Unreal Editor unstable but I have to use it because of FBX import not working in previous version.

You can try deleting the Saved and Intermediate folders and then attempting to open your project again.

OK thanks.
I had not seen your answer, so I’ve unziped last version, recreated C++ classes and blueprint one by one until it finally worked !
Next time I will delete those directories first… Too late ! but I’m happy because I did not lose any work.
