When opening Unreal Editor on Linux, the Project Browser opens but is completely unresponsive. Shortly afterwards the editor will crash. If you use the -nocef command when opening the Editor, everything works appropriately.
The user is able to select an existing project or create a new project in the Project Browser
The Project Browser is unresponsive and the engine crashes
