I get this error when trying to launch UE4Editor.exe. I have compiled from sources UE 4.12.5. I also have installed the same version of UE via Epic Launcher, but it’s not usable for me because of Engine compile errors appearing while compiling a custom plugin. I hope these two UE installations don’t conflict.
What is the cause of this error? How to solve it?
Would be glad for any help…
