Editor always crashes on launch

Hi,

since yesterday I am not able to run UE4 anymore. I am currently using UE4 4.7.6.

I am running Windows 8.1 (64 bit) on a i7 Quadcore with 8GB of RAM and GTX 860M with 2 GB dedicated video memory.

It doesn’t matter how I try to start the editor:

  • using Launch in from Launcher
  • open a project from Launcher
  • start editor directly from Binaries folder

It always goes to 35% before crashing all the time with the same call stack. I have attached a log file while trying to load a project. I wasn’t allowed to attach the dump file produced. I also let crash reporter send a report.

I couldn’t launch the editor for quite some time (it crashed) but opening a project worked fine and from there I could also create new projects. But now I can’t do anything with UE4. I even uninstalled and reinstalled everything on another partition but no success.

2 days ago I installed TADP and while packaging a project for Android my computer froze completly so I had to turn it off hard. I have already checked and repaired drive C:. I assume that something is screwed up in my system but don’t know what. I also have tried to remove intermediate files either from projects I tried to open or the derived data cache. No luck at all.

Any idea or suggestion is highly appreciated because I want to continue working with UE4.

Thank you very much.

Best regards,
Maik.
