Project Crashing on Startup

Hey guys! I’ve had some problems with UE4 4.10
I was saving a project for a class I’m taking on a hard drive when it seems like the flash drive un-formatted itself during the save process. I tried to restart Unreal Engine 4 and it asked me to recover some models, I tried to recover everything I could but now it crashes every time I try and load up my project. I’ve spent quite some time on this so I’m really hoping I can recover the project. Here is what the Crash Reporter says:

Thanks for the help in advance!

Start deleting folders:) And you need to probably regenerated your project (or you could try that first), by right clicking on the uproject and click generate project files.Folders to delete, in order, one by one:

  • Saved/Config
  • Intermediate

Those are the only two I would suggest messing with tbh, you should be able to regenerate your project after deleting those, unless your project is severely corrupted. Of course, you said you saved it to a HD, well, you should have a save somewhere else right?

Yeah!. Thanks for the quick response. Appreciate it a bunch!
