UWP build crashes: System.ExecutionEngineException

Hi,

using:
* Unity 2017.4.4f1 (64-bit)
* UWP
* XAML
* Scripting Runtime: Stable (3.5)
* Scripting Backend: .NET
* API Level: 2.0, 2.0 Subset, 4.6
* C# Project export and NOT.
* Building with VS 2017.

I keep getting crashes after x seconds:
An unhandled exception of type 'System.ExecutionEngineException' occurred in WHATEVER, e.g:


An unhandled exception of type 'System.ExecutionEngineException' occurred in WinRTBridge.winmd

18.  

Or e.g. in:
An unhandled exception of type 'System.ExecutionEngineException' occurred in UnityEngine.IMGUIModule.dll
(IMGUI, not sure why ... must be the built in debug console, we don't use IMGUI.)




Now I think the issue could be related to
https://forum.unity.com/threads/uwp...own-on-system-reflection-monoproperty.528517/
but I cannot post in that thread.

It reads like, the solution is to use IL2CPP ... can anybody confirm this?
I gave it a quick shot and it seemed more stable, but my problem is, we use Vungle and it seems, Vungle doesn't support IL2CPP.


I am also seeing suspicious logs:
"Exception thrown: 'System.IO.FileNotFoundException' in System.Private.CoreLib.ni.dll" (my second sample exception is exactly in that dll ... coincidence?)

Or what about this:
"Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak"



Grateful for any tips!

Thanks!

 

Hi,
thanks for the reply.
We use tons of extensions and this project is an upgraded one from 5.6. So possibly still some extensions not working but compiling ...

I have done some further research and I also have crashes with 5.6 and our current codebase. We recently added asset bundles* and some other stuff, so I am beginning to think, this could be related to that (all other platforms work fine though!).
But I am not sure, if these crashes themselves (5.6 <-> 2017) are related.

And on top of that, a new Windows SDK got installed which messed up the exported projects ... I figured that one out, thanks to forum search

I'll keep this thread updated.


*: Just yesterday I also found out, that when building AssetBundles, it is relevant to have the scripting backend set correctly.

 

Hi,

@Tautvydas-Zilys I tried doing some native debugging, but that isn't my world. I submitted a bug report case 1045982 (UWP (ARM) Possible heap corruption with scripting backend .NET).

Would be more than grateful if someone could help us out and tell us if it's an extension issue, Unity or Microsoft
Edit: Or tell us, if we arent to expect any support for Windows 10 ARM, cause maybe MS themselves arent interested anymore.
