UE5 热重载系统有bug

UE5热重载系统或者说GAS系统有bug

在网络游戏条件下，GAS某些功能莫名其妙无法实现网络同步，导致空指针错误，恶心死了

本来就焦灼，在这排查了一个小时

void UAuraAbilitySystemLibrary::InitializeDefaultAttributes(const UObject* WorldContextObject, ECharacterClass CharacterClass, float Level, UAbilitySystemComponent* ASC)
{
	AAuraGameModeBase* AuraGameMode = Cast<AAuraGameModeBase>(UGameplayStatics::GetGameMode(WorldContextObject));
	if (AuraGameMode == nullptr) return;

	AActor* AvatarActor = ASC->GetAvatarActor();

	UCharacterClassInfo* CharacterClassInfo = GetCharacterClassInfo(WorldContextObject);
	FCharacterClassDefaultInfo ClassDefaultInfo = CharacterClassInfo->GetClassDefaultInfo(CharacterClass);

        /** 逻辑代码省略 */

}

void UAuraAbilitySystemLibrary::GiveStartupAbilities(const UObject* WorldContextObject, UAbilitySystemComponent* ASC)
{
	AAuraGameModeBase* AuraGameMode = Cast<AAuraGameModeBase>(UGameplayStatics::GetGameMode(WorldContextObject));
	if (AuraGameMode == nullptr) return;

	UCharacterClassInfo* CharacterClassInfo = AuraGameMode->CharacterClassInfo;
	for (TSubclassOf<UGameplayAbility> AbilityClass : CharacterClassInfo->CommonAbilities)
	{
		FGameplayAbilitySpec AbilitySpec = FGameplayAbilitySpec(AbilityClass, 1);
		ASC->GiveAbility(AbilitySpec);
	}
}

在这段代码里，只要我试图把

	AAuraGameModeBase* AuraGameMode = Cast<AAuraGameModeBase>(UGameplayStatics::GetGameMode(WorldContextObject));
	if (AuraGameMode == nullptr) return;

封装成函数，比如

UCharacterClassInfo* UAuraAbilitySystemLibrary::GetCharacterClassInfo(const UObject* WorldContextObject)
{
	AAuraGameModeBase* AuraGameMode = Cast<AAuraGameModeBase>(UGameplayStatics::GetGameMode(WorldContextObject));
	if (AuraGameMode == nullptr) return nullptr;
	return AuraGameMode->CharacterClassInfo;
}

就报空指针异常，跟有大病一样，甚至都不知道为什么
