When exiting PIE, the editor gets stuck for a long time

When exiting PIE, the editor will be stuck for a long time. It is a problem with requesting data. We can only add a timeout, but we don’t know if it is correct. Do you think we should add this judgment?

UnrealAssetAccessor.cpp

return asyncSystem.createFuture<std::shared_ptrCesiumAsync::IAssetRequest>(
[&url, &headers, &userAgent, &cesiumRequestHeaders](const auto& promise) {
FHttpModule& httpModule = FHttpModule::Get();
TSharedRef<IHttpRequest, ESPMode::ThreadSafe> pRequest =
httpModule.CreateRequest();
pRequest->SetURL(UTF8_TO_TCHAR(url.c_str()));

    pRequest->SetTimeout(10);
    
    for (const auto& header : headers) {
      pRequest->SetHeader(
          UTF8_TO_TCHAR(header.first.c_str()),
          UTF8_TO_TCHAR(header.second.c_str()));
    }

Adding a timeout is ok, but it's probably better to figure out why the server is taking so long to respond to some requests in your case. That's most likely the root of the issue here.
