Project Won't Open - Replicated [resolved]

I was working on a practice c++ project with Unreal Engine 4.23 Preview and it would compile successfully, but when I attempted to launch the project it would load 95% of the project and then silently terminate.

I checked the logs and discovered that the editor crashed due to a variable having replication implemented, but it didn’t have the “Replicated” specifier.

ReplicationActor.h

#include "Net/UnrealNetwork.h"
virtual void GetLifetimeReplicatedProps( TArray< class FLifetimeProperty > & OutLifetimeProps ) const;

// WARNING: Variable replicated without "Replicated" specifier
UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "Practice")
FString Message;

ReplicationActor.cpp

void AReplicationActor::GetLifetimeReplicatedProps(TArray<class FLifetimeProperty>& OutLifetimeProps) const
{
    // WARNING: If "Message" doesn't have the "replicated" specifier
    // the project will crash on launch
    DOREPLIFETIME(AReplicationActor, Message);
}

I added the “Replicated” specifier to the variable. The Crash Reporter eventually appeared, but I will submit a bug report.
