Toggle visibility of actors failed sometimes

Hi there, I have created a new function to toggle the visibility of an actor class. But it failed to toggle one or two actors off and on sometimes, even though I have used a while loop. can someone help me?

Below is my code:

void UMyBlueprintFunctionLibrary::ToggleWalkerOnAndOff(TArray<ACharacter*> Walkers)	
{
        for (auto& Walker : Walkers)
        {
            bool Visibility1 = true;
			bool Visibility2 = true;
			while (Visibility1 == Visibility2) // make sure that the targeted actor is toggled once
			{
				Visibility1 = Walker->GetMesh()->IsVisible();
				Walker->GetMesh()->ToggleVisibility();
				Visibility2 = Walker->GetMesh()->IsVisible();
			}
			Walker->SetActorEnableCollision(true);       
        }
	
}
