Just solved this problem on my end. Surprisingly i was also doing http requests, so i guess we had the similar setup:

//Backend.h:

UCLASS()
class TSARSTVA_API UBackend : public UObject
{
	GENERATED_BODY()
	
public:	
	UBackend();

	FString RequestAddress;
	FString RequestPort;

	void MakeRequest();
};

// mygamemode.h
UCLASS()
class TSARSTVA_API AMyGameMode : public AGameMode
{
	GENERATED_BODY()

public:
	AMyGameMode ();

	UBackend* Backend = nullptr;

	void BeginPlay() override;
};

//mygamemode.cpp

AMyGameMode::AMyGameMode()
{
	Backend = CreateDefaultSubobject<UBackend>(TEXT("Backend"));
}

void AMyGameMode::BeginPlay()
{
	Super::BeginPlay();

	FTimerHandle _;
	GetWorld()->GetTimerManager().SetTimer(_, [this](){Backend->MakeRequest()}, 3, true);
}

and the reason was that garbage collector was killing my UBackend right after creation, corrupting a few symbols in the strings, but without a crash. So you just have to mark your UBackend* as UPROPERTY() to avoid situation where uobject have no tracked references in the ue system
