How to change skeletalmesh and animblueprint at runtime?

I can change skeletal mesh, but changing of animblueprint always fail.

class .h

UPROPERTY(VisibleDefaultsOnly, Category = Mesh)
TSubobjectPtr<USkeletalMeshComponent> CurrentMesh;

UPROPERTY(EditDefaultsOnly, Category = Mesh)
USkeletalMesh* FlagMesh;

UPROPERTY(EditDefaultsOnly, BlueprintReadWrite, Category = Animation)
UAnimBlueprint* FlagVIM;

class .cpp

CurrentMesh->SetSkeletalMesh(FlagMesh); //works
CurrentMesh->SetAnimClass(FlagVIM->GetAnimBlueprintGeneratedClass()); //fails

Also i have tried:

CurrentMesh->SetAnimClass(FlagVIM) //compile failed because UAnimBlueprint* is not a UClass*

And also if i set

UPROPERTY(EditDefaultsOnly, BlueprintReadWrite, Category = Animation)
UAnimBlueprintGeneratedClass* FlagVIM;

CurrentMesh->SetAnimClass(FlagVIM) //fails inside SetAnimClass() function

How to change it right?

I Might be completely on the wrong track here, but try to get all the Blueprints during your initialization via:

 AFriendly1::AFriendly1(const class FPostConstructInitializeProperties& PCIP)
    : Super(PCIP)
    {
    
        static ConstructorHelpers::FObjectFinder<USkeletalMesh> FriendlyMesh(TEXT("SkeletalMesh'/Game/Character/HeroTPP.HeroTPP'"));
        	static ConstructorHelpers::FObjectFinder<UBlueprint> MeshAnimBluePrint(TEXT("AnimBlueprint'/Game/Character/HeroTPP_AnimBlueprint.HeroTPP_AnimBlueprint'"));
Mesh->SkeletalMesh = (USkeletalMesh*)FriendlyMesh.Object;
Mesh->AnimBlueprintGeneratedClass = (UAnimBlueprintGeneratedClass*)MeshAnimBluePrint.Object;
    
    ..........
    }

and then just update the properties when needed during runtime by referencing to these.

This is strange way, i do not want to find it, i want to set it and use it.

Still the same in 4.1.
