Hey Twibbz,

Are you using 4.7.6 version of the Engine? Are you working out of the Epic Games Launcher or from our source build from GitHub? Does this only occur when you open this specific project, or does it occur when you open freshly created templates?

Also, have you tried opening the UE4 Editor.exe from its nested location? (example: D:\Epic Games\4.7\Engine\Binaries\Win64) If you haven’t tried opening the editor up from here, could you please do so and attempt to open the project you’re having trouble with?

Looking forward to hearing back from you, thanks!

Epic Games Launcher. Opened the engine from the nested location and it somehow seemed to fix it. Many Thanks
