Unreal Engine has stopped working when opening my project

Hey guys,
I’m experiencing a really annoying problem right now and probably my project is totally fu**ed up :frowning:
I worked hard on a project since yesterday and everything worked fine. But now the project has crashed and I couldnt open it again because there’s the error: “UNREAL ENGINE HAS STOPPED WORKING” after initializing(70%).
It was a quite hard exercise for my PC before it crashed. I was copying a lot of actors at once, but normally my PC can do this.
Cloning the prohect or copying the files doesnt help. Other projects could be opened.

Specs:
8GB RAM
i5 4460
R9 380 4GB

I already updated all the drivers and got some space on my nearly full SSD.

I hope you can help me!
Thank You

Try to debug your editor. You can do this by opening the visual studio solution file (.sln). When you are in visual studio you can hit F5 to debug the editor. It should start and crash as before, but when it crashes you will be taken to the code that causes the crash instead of the blug splat. If you look at the callstack, you might find a function of yours (a constructor most likely) that causes the problem.
