Here is solution to avoid crash when opening project.

Comment line 38-44 in OculusVRDartsGame\Source\Darts\OculusOSS.cpp. The influence of this opration is unknown when project running .

OnStartSessionCompleteDelegate = FOnStartSessionCompleteDelegate::CreateUObject(this, &AOculusOSS::OnStartOnlineGameComplete);

OnDestroySessionCompleteDelegate = FOnDestroySessionCompleteDelegate::CreateUObject(this, &AOculusOSS::OnDestroySessionComplete);

// ovrMessage_Notification_ApplicationLifecycle_LaunchIntentChangedHandle =
// 	OSS->GetNotifDelegate(ovrMessage_Notification_ApplicationLifecycle_LaunchIntentChanged).AddUObject(this, &AOculusOSS::OnApplicationLifecycle_LaunchIntentChanged);

// if (!ovr_RichPresenceOptions_Handle)
// {
// 	ovr_RichPresenceOptions_Handle = ovr_RichPresenceOptions_Create();
// }
