Impal3r,

In the Epic Launcher click the drop down button next to the launch button for the engine and verify your version. If you did not already maybe try updating to the latest hot fix of 4.14.1

Remove the Intermediate and saved folders under your project folder and try re-opening the engine again.

If this doesn’t work remove the hidden folder under the users Appdata → Local → UnrealEngine. Keep the others there. This will revert the engine to open like the first time again.

If this doesn’t work, run the direct executable for the editor only under the Program files x86 folder, UE4Editor.exe and run as administrator

hope this helps.

I already did this.
