Editor crashing when opening a specific level

Hi ! I’m here to report a bug I just get meanwhile everything was OK hours ago.
The thing is that I got several levels in my game, and the whole Unreal Engine is crashing when I open the level (in game or in editor) or just when I do a right click on the level.

Here is the crash report when it happends : link text

It’s very annoying since I can’t edit it to find the problem. Also, It happend several times lately, when opening a new level, this one stay “unsaved” (with the * near its name) meanwhile others auto-save correctly.

Thank you in advance for replying !

Hello,

Have a look at the accepted answer to the post linked below. This issue has been reported in the past, but it seems to be an issue with the Light Component on a Directional Light actor becoming null. If you could provide steps as far as how to reproduce it in a clean project, please do so.

Have a great day

Hi ! Thank your for replying. It didn’t helped a lot but I succeed to fix it by creating a new map and redoing all the Level Blueprint.
However, something really strange happend.
Here’s the scene :

  • The Map “A” was bugging, crashing when doing any click on it.
  • I created the Map “B” by copying/pasting all meshes, lights and so on from a previous version of the Map “A”.
  • I tried to copy/past the Blueprint level from the old A to the B and at this moment, the B editor crashed. Even if the less important node.
  • However, by redoing all the Level Blueprint node by node without copying, everything seems to be working.

Not sure if it will be helpful in any way but I hope so.
