Editor crashes on launch

Development Programming & Scripting
1

Ever since the last Launcher update the editor crashes when I try to open my project. This does however not happen when I create a new project or open one of the marketplace projects. The Project was using the ‘Basic Code’ template.

I already tried rebuilding my custom code but that did not help.

I get the following crash report:

We apologize for the inconvenience.
Please send this crash report to help
improve our software.

I would be grateful for any help.

EDIT:

I tried running the project from Visual Studio and got the following error message:

There is of course more but I hope this is the usefull part.

EDIT2:

I tried to remove the asset mentioned in the crash report from the content folder. After that the editor is loading correctly. Unfortunately, after I move the asset back in the content folder the editor crashes again. This also happens when I use the backups of that asset in the Save/Backup folder.

Possibly related to the same issue I had. My work around was to comment out all of my code and rebuild, then uncommenting->rebuild each section. Found that some parts of my code were trying to get information from something that didn’t yet exist. (Actually, in my particular case, still can’t get it to find the data I need)

Anyway, seems that on editor load it’s also runs your game code and if it hits something that references something that’s not there…crash. So wrapping stuff in “if (thingexists()) {}” got my editor to load.

Hi ,

What version of the Editor are you using? Are you able to run your project (just the project, not the whole solution) in debug mode from within Visual Studio? Do you receive any error messages when you do so?

I edited the original post and added the error message.

The launcher version is 1.2.2-2080581+++depot+UE4-LauncherReleases
I use Unreal Engine 4.1.1

Thank you for the comment,

I tried that. Unfortunately it did not work. When I try to interpred the error message it looks like the problem is connected to one of my Blueprints. Unless there is a way to modify Blueprints without the editor I need to get the editor running somehow.

Hi ,

Would you be able to zip and upload the asset that seems to be causing the issue?

Sure, here is the link:

When I move the file to a subdirectory the editor starts normally and complains that the file is missing. If I put it back to the correct directory while the editor is running everything works as expected untill I try to load another map where the asset is also used or I try to restart the editor.

Hi ,

The Blueprint came with some errors, where nodes are referencing other functions that seem to be contained in different Blueprints. I replaced the nodes that had errors with some Print String nodes, but I was not able to see any crashing taking place.

Would you be able to try putting the Blueprint into a new project from a template and get it to where it should be working with as few additional Blueprints/assets as possible? The issue may be related to one of the functions that I don’t have, or another game asset referenced by the Blueprint.

I was not able to reproduce the crash in a new project yet. I took the opportunity to start from scratch again since I was not happy with my implementation anyway and it only took a few days to get the game to the same state as before. So the crash itself is not causing too much trouble. I was just hoping to find out what caused the problem so I wont make the same mistake twice.

Hi ,

I just wanted to follow up with you and see if this issue is still affecting you. I will be marking this issue as resolved for tracking purposes, but if you still need any help with this, please feel free to reopen this.

Thanks,
