Engine Crashes when moving a StaticMeshActor into a folder

I see,the thing is iam using the Epic games launcher so i downloaded the engine through that,is it possible to find the installation somewhere or does it automatically download and install? By the way just out of curiosity if my problem still occurs in a newly created project (i tried the starting content attempt in a new project) how would testing in other specs help? I mean…could my engine make corrupted files while creating a new proejct?
