When trying to build a blank scene with only a cube in it, UE4 Fails to launch into the Magic Leap. I’ve installed all the necessary components and SDK files into the proper place and updated the SDK directory in the project settings. When trying to Launch to Magic Leap One I get the following errors and the launch fails:

Hi!
I just ran into this problem and was able to solve it by and adding mycert.cert and mycert.privatekey to Build/Lumin folder and editing Conig/DefualtEngine.ini
