Why does my unreal engine keep crashing?

UE4 keeps crashing on my 14" MacBook Air. If I load a project it loads and it closes the UE4 editor. It only worked proper the first time I opened it. I don’t have the recommended RAM but that shouldn’t bother me from using it, right? Can someone help me?

low memory cuz crash for any application even when working with maya or 3dsMax

however, maybe someone could help u and confirm this issue
