Cannot open source file "CoreMinimal.h"

[Samuele_Giuseppe_Lus]

Hello! I’m using UE5.0.3 on my Mac.When I open any c++ project file of Unreal Learning Kit(Obstacle assault in the course) I have these errors:
cannot open source file “CoreMinimal.h”
cannot open source file “GameFramework/Actor.h”
cannot open source file “MovingPlatform.generated.h”
I also don’t have the ability to select any build task.
