UWP Game Crashes upon Loading a New Scene. in Master Configuration.

Hi All,
I have an issue. Every time I build for Master Configuration ad run my game, It crashes once i try to load a new scene after launching the game. the build file errors are attached and also a screenshot of my Visual Studio Editor is shown below.

 

Hi Aurimas,
I did as you suggested and this is the result

 

Hi Aurimas,
Once I get the game going in debug or master's configuration mode, with the .NET Native and code optimization checked, it works and I begin to see numerous " Skipped loading symbols. Module is native, and native debugging is currently disabled." prior to the Splash Screen of Unity showing. The first scene gets loaded, I click a button to Load the next level. It begins the loading process then crashes. The Screenshot attached shows the error.

Hi Tomas1856,
this is a real bummer. Is it possible to build the game as an exe file and convert it using Microsoft Project Centennial??

 

Thanks I will try the il2cpp. any pointers for that??

 

I encountered a similar error over the past week. I thought it was being caused when the Scene Manager loaded a new level. This turned out to be and not be the case.

After the SceneManager loads the new level, but before it displays the new level it Destroys all the game objects in the scene it is leaving. However it appears the .Net Native does not properly Destroy the Gameobjects.

In my case I had 2 Tweens on 2 Buttons under the Canvas. I removed the scenemanager and performed a destroy on the Canvas object and the same error occurred.

So my first attempt was to Manually destroy each object in the canvas/Panel. This caused the error to go away. Even after I re-added the Scenemanager.

Upon further inspection I saw the Tween and manually killed the tween prior to the Scenemanager load. I then removed all of the manual destroy calls, but kept the Tween Kill calls prior to the scene manager load and I did not encounter the error.

A side note I have had tweens that were effecting the scale of the objects that did not cause the problem.

The error for me appears to happen when I was effecting the "fade"/Transparency of the object.

**UPDATE** The errors root cause appears to have came from creating the Tween(Component) in the START() function of a script. When I placed the same Component on the game Object in the Unity Editor the .Net Native was able to properly Destroy them, however if it was created/added in the script .Net native was not able to handle it **ENDUPDATE**

So to recap. To help debug this issue Comment out the SceneManager, Then you need to go each item and manually destroy each game object to find out which object is causing the issue. Once you find it beak the object down to fine out which sub gameobject is causing the issue. if you can find the specific object you can usually manually destroy the object to "work around" the issue.

Hope this helps for anyone who encounters this issue.

 

Yes... I have the exact same problem, and it happens because of DOTween.

It seems DOTween uses some kind of Try Except to Kill Active Tweens when the Current Scene Change, but this seems to be ignored when using .NET Master Configuration.

To solve this problem, You can do everything you said, or to make it more easy, just ADD an OnDisabled event to any GameObject on Scene with DOTween.KillAll(true).

 

Hi Tomas,
I was checking through the release notes for VS2015 Update 3 and I did not see anything relating to the issue. Do you know if they have addressed the issue.

 

So, does that mean Unity will carry out the fix and warn developers on it. Or has Unity already carried out the fix??

 

We are hitting this as well. It seems to have started happening only recently for our project.
Is there a known workaround for this?

 

Sure.

 

No, we don't have the source code for this DLL.
It also doesn't sound reasonable that we can avoid all exceptions entirely, something is always bound to fail. We always need to be able to catch the exceptions to get useful telemetry and crash reports that help us fix the problems.

Why has this only started happening recently? Is it due to the latest Unity build in particular?

 

Actually the source is available on GitHub (by the creator), see: https://github.com/Demigiant/dotween.

I'm actually using the source to try to build using .NET Native, but with no luck so far. The errors are..."hard-interpreted". Hopefully someone can get this to work?

 

I just ran into this, is there a fix or workaround?

 

Oh thank god, I am currently on 2017.2.1 what version should I upgrade too?

 

Oh that is too bad, my issue behaves the same, it works in Debug mode but in Master one of my scenes crashes on load. There are no errors in the Editor or in Debug mode. Having a hard time identifying the problem

 

I was able to get my game to work by updating Unity to 2017.3 and then choosing il2cpp instead of .NET. That solved the issue, not sure if it was the newest version of or the il2cpp but it works either way.
