My unreal engine 4 says that it is missing content and can’t launch. I am confused because I didn’t delete anything from my UE4 files. It says it failed to find /Engine/EditorMaterials/HelpActorMaterial, what do I do? Do I reinstall UE4 or is there another way? Please help.

The full error message:
Default Property warnings and errors:
Error: CDO Constructor (DocumentationActor): Failed to find
/Engine/EditorMaterials/HelpActorMaterial

When I try to launch it says I’m missing the content to launch it.

PLEASE HELP ME!!!

Can you verify your engine on Epic Launcher?

Try verifying the engine in the launcher, this will start a process where the engine is scanned for any missing or corrupted files and if there are missing or corrupted files detected the engine will install the right files and put them in the correct path location. If this doesn’t work for some strange reason then you are going to have to reinstall the engine.
