SwapChain in UWP - Cannot Unload/Load Unity Runtime again

As mentionned in the title, I'm integrating a Unity3D Window inside a XAML Page.

I'm able to load it, and interact with it between both UI-App threads. But my problem is that: I cannot load another Unity3D Window in the same page, or another page unless if I unload the Unity Runtime using: Application.Unload()

Which is exactly what i'm doing here:

Code (CSharp):

1.  
2.         public static void UnloadUnity()
3.         {
4.             if (AppCallbacks.Instance != null)
5.                 AppCallbacks.Instance.InvokeOnAppThread(() =>
6.                 {
7.                     UnityEngine.Application.Unload();
8.                 }, false);
9.         }

Then when I want to load Unity inside another SwapChain using this:

Code (CSharp):

1.  
2.         public static void LoadV2(SwapChainPanel swapChainPanel)
3.         {
4.             // Setup scripting bridge
5.             //if (_bridge == null)
6.             _bridge = new WinRTBridge.WinRTBridge();
7.  
8.             if (appCallbacks == null)
9.             {
10.                 appCallbacks = new AppCallbacks();
11.             }
12.  
13.             appCallbacks.SetAppArguments(_appArguments);
14.             appCallbacks.SetBridge(_bridge);
15.  
16.  
17.             appCallbacks.SetSwapChainPanel(swapChainPanel);
18.             appCallbacks.SetCoreWindowEvents(Window.Current.CoreWindow);
19.             if (!appCallbacks.IsInitialized())
20.                 appCallbacks.InitializeD3DXAML();
21.  
22.             Window.Current.Activate();
23.         }

I get this error (if I'm loading it in the same page on another SwapChainPanel)
GetManagerFromContext: pointer to object of manager "PlayerSettings" is NULL (table index 0)

(Filename ........./unity/build/Runtime/BaseClasses/ManagerContext.cpp Line: 89)
Or this error (if I navigate to another page with a swapchainpanel)


I'm using Unity 2018.4.3f1 along with Visual Studio Enterprise 2017
Thank you.

 

Hello, have you solved this?
