How do I stop the editor from crashing?

Everything was going fine and then the game crashed while building the lighting. I believe I was low on disk space.

Now every time open the game in the editor it crashes when I try and edit something.

The following crash report is generated:

We apologize for the inconvenience.

Could you probably post your log file? Project → Saved → Log

I’m not sure if that link is working, please let me know.

I really need help on this one. My deadline is coming up.

is their a way to revert back to the last time it worked? all my other projects are working fine

Hi LiquidJoy -

Before your Light Build which was immediately before your crash, did you delete something like an Atmospheric Fog and then re add that item to the level? If there is absolutely anything you can think might be important about the steps you took toward the crash, please let us know

Thank You -

I was resizing a group of static mesh’s. I then clicked the save icon followed by the build icon on the top tool bar. A crash occurred while building. I noticed at this point that I only had 50mb left on the SSD that the game was stored on.

I freed up some space and opened the game in the editor, attempted to Alt drag a geometry object to copy it. the crash happens the moment I click on the object while holding Alt.

I cloned the project onto a different drive using the clone option in the Unreal editor launcher but the same crash occurs. it also crashes when I click build after the initial build status bar has reached the end (0.5 seconds)

. It also crashes when I drag a static mesh from the left hand static mesh list into the level. It also crashes when I click the save button.

However it does not crash when I click play, I can play the game without a problem. I just cant edit anything without it crashing.

Hi LiquidJoy -

So if you can play without crashing, Have you tried building lighting again? Also if you can select items in the editor without crashing can you CTRL-A and then copy and paste into a new map, or does the CTRL-A cause a crash as well?

I feel that due to the lack of HD space something got corrupted during the light build and that is what is causing the crash? IF you are able to fully build lighting it might invalidate the file that is causing the crash and replace with a functional version.

Let me know -

CTRL A causes the same crash.

Building the lighting causes the same crash

Hi LiquidJoy -

Try to find your unreal projects directory and delete the following directories: Intermediate and Saved. This will not delete any map or content information but should remove some of the light build information.

Once deleted,open up your project again and see if you can edit anything.

I Deleted Intermediate and Saved, opened the project and it crashed when I tried to edit as per usual.

I’m thinking of remaking the game from scratch.

Hi LiquidJoy -

I believe I have narrowed down your issue to a duplication and overwrite error that will cause a crash and an inability to recover the project. I have not successfully reproduced your exact issue yet but the call stack leads me to another issue which was resolved with 4.2.

I cannot 100% guarantee that you would be able to open the project in a newer version of the engine but it is possible. If you are willing and able, I could test the project here to tell you if the issue is resolved in a newer version of the engine. I would need the Content and Config folders as well as the *.uproject file.

As of know though with the version you are currently running of the engine, I do not believe the project is recoverable.

I have already started to rebuild the game. I should be back on track after today.
