Project crashes on launch at 79%

Hello, I’m working on a cinematic project for VR(rift) on UE4.15

After trying to compile and failed, I tried to disable some plugins that were of no use for my project.
Unreal asked me to restart the editor. So I did and now I can’t launch my project, it crashes everytime at 79%.

Here’s the log file :
