Hey srodriguezdiseno ,

Make a backup of your project folder then do the following:

  1. With the Editor/Launcher closed, delete the Config, Intermediate, and Saved folders from your Project Folder
  2. Double-click the .uproject file to open it
  3. If it fails to open, Open the Launcher
  4. Navigate to UE4.10 in the Library tab of the Launcher
  5. Select the down arrow on UE4.10 icon and choose “Verify”
  6. After verifying the UE4.10 version of the Launcher, try opening the project through the Launcher.
  7. If it does not open, delete the Config, Intermediate, and Saved folders and try to open through the Launcher again.

Try these steps and let me know if they resolved your issue.

Thanks,

Steve H.

It was a corrupted imported skeletal mesh, I deleted that folder and reimported again, working fine after that, I dont know why it ocurred since Im now working with the same file without problem.

Glad you got it working and thanks for posting your solution. I have converted your response to the answer to this thread.
