Engine crashes when opening any project

Hey, every time I try to open any of my projects they crash with this message. I tried creating a brand new project and get this same message. Anyone have any ideas?

Unknown exception - code 00000001 (first/second chance not available)

Hi Dundii,

I’d suggest taking the following steps:

  1. With the Launcher closed, move your “Unreal Projects” folder to your Desktop temporarily
  2. Uninstall the Unreal Launcher and remove any remaining folders from the install directory
  3. Re-download and install the UE4 Launcher (I’m assuming your downloading the Binary version and not from Source from GitHub)
  4. This should install with UE 4.10.4.
  5. Launch 4.10.4 and open a blank Third person Template (if possible)
  6. Close Third Person Project
  7. Now you can go back to the Library at the top of the launcher and reinstall UE 4.9.2
  8. Install UE 4.9.2 and open a blank Blueprint project
  9. If successful, Close UE4 and copy one of your original projects from “Unreal Projects” on your desktop and paste the newly created “Unreal Projects” in your Documents folder
  10. Open the Launcher, Open UE 4.9.2 and, once open, Open the project you restored from the desktop
  11. If successful, repeat steps 9 & 10 until all are restored or until you identify the corrupt project

If you run into problems to where you have the same error upon trying to reinstall, we will need the following information:

  1. Are you downloading the binary Launcher from the website or building from source via GitHub?
  2. Are you installing the engine on one drive and storing your project files on another?
  3. Please cut and paste the entire callstack from the Crash Reporter window into a doc and link here (This will include your Machine I.D. and Epic User I.D. at the top)
  4. Please provide the following logs if available:
    a. “UE4.log” Located: Engine\Saved\Logs
    b. “ProjectName.log” Located: ProjectName\Saved\Logs
    c. Your dxdiag

Please try the above troubleshooting steps and, if they do not work, supply as much as of the requested info as possible in order for us to identify the source of the problem as efficiently as possible.

Thanks,

.

Hi Dundii,

Since we have not heard back from you in a few days, I’m marking this post “resolved” for tracking purposes. However, if you still are unable to open a project without the engine crashing, please respond and list what troubleshooting steps you were able to try and, if none helped, provide as much information from the second list as possible.

Thanks,

.
