I tried to revert to a place where the editor was working using git and the editor loading is still failing. I don’t understand. If I used git in the editor, why does reverting my source and hopefully editor settings, back to a commit where the editor worked still report the same error? It makes me think that the editor is saving something or is on its own branch.

I was able to overcome this by deleting everything except the Contents folder, the Source folder, and the uproject file. After that, All I had to do was open the project from the editor and let Unreal rebuild the project for me. I know that’s probably overkill but I have no idea which specific file or folder is causing the editor loading to keep tripping up on the same mistake.

I’ve just encountered this problem and able to solve by doing “make” in your UE4 root directory. Won’t last as long as the first time you’ve made that. By doing so you can solve this without deleting anything risky.
