Editor Crashes when opening Level

Development Platform & Builds

Hi there,

I worked ages on a level and suddenly I can’t open it in the editor any longer. As soon as I try the entire Editor crashes.

After researching, it seems some mesh or BP was corrupted although I haven’t the slightest idea which one.

I have backups but I have no idea how to export a Map to another Project.

Do I have to start the entire level over again? I really just want to get back to work.

Regards,

Any help would be massively appreciated!

Hello,

Could you please cause the crash to occur again, and provide the folloiwng information:

  • The logs from your project’s Saved->Logs folder
  • If you are getting a crash reporter window, provide your Machine ID and ensure to hit Send & Close on the report.
  • Are you able to reproduce this issue in a clean project?
  • If so, please provide a detailed list of steps.

In the meantime, you can make a copy of your current map file and store it somewhere else, and try to use one of the backups stored in your project’s Saved->Backups folder (if a backup exists). To do this, just grab the .umap file and move it into your content folder.

Hi there Sean!

Sorry for the delay…hope you can still help.
I’m able to open the map in a new project however, I still can’t open it in my current project.

Attached is the log. It seems to reference missing a blueprint not associated with the crashing map.

Best,

Hello!

Of course we can still help.

Are you getting a Crash Reporter window? If so, please provide your Machine ID and ensure to hit Send & Close on the report.

Here’s the error I see in your log file: LoadErrors:Error: Error /Game/Characters//deVriesBP : Can’t find file for asset. /Game/Blueprints/Screens/Subtitles/CollegeGreen1

I’d be surprised if that was the reason for the crash, but it’s worth investigating.
Ensure that you don’t have any extraneous references to that asset.

Thank you so very much Sean!

The MachineId is: A84DE02A47273BA8382F76AEB3C79FFB.

I would be suprised also if a blueprint could cause a map to fail to open. Please do let me know what you find. I appreciate your support!

Best,

Have you tried removing any reference to the asset mentioned below:

Here’s the error I see in your log file: LoadErrors:Error: Error /Game/Characters//deVriesBP : Can’t find file for asset. /Game/Blueprints/Screens/Subtitles/CollegeGreen1

Also, something you can try is migrating your content into a new project if the map is working in a clean project and see if the same crash occurs. It could be something in the project that was corrupted.

Finally, you can also right click the Content folder in the content browser and select the Fix Up Redirectors in this Folder option.

Let me know if that helps

Hello again! Thank you so much for your help.

It appears the Map would not open until I placed the missing BP from an older version into the current game directory.

That fixed it though and I was able to re-open the map.

I wouldn’t have thought of it without your help, so thank you again!
