UWP exported app does not work in release mode

[vnen]

I'm having a hard time figuring out this problem, so I'll leave this issue open until I (or someone else) can solve it. This is valid for 2.1 and 2.2, so I assume it is the same for master.

The UWP app exported does not run when installed, it just crashes on opening. The only debug info I have is the EventViewer, which does not help at all:

ActivateApplicationForContractByAppIdAsUserWithHost of the app Godot.Engine.Test_q1xfrwf3pzxew!App for the Windows.Launch contract failed with Access is denied..

Trying to debug the installed app from Visual Studio (via Debug > Other Debug Targets > Debug Installed App Package) is not helpful because it runs fine there! So there's something fishy about how apps are launched that is a mystery (at least for me).

Summing up what I know:

1. The app runs fine if compiled with target=debug or target=release_debug build, but crashes on opening with target=release.
2. The target=release build runs fine from Visual Studio, even when debugging the installed app.
3. Compiling the release with /SUBSYSTEM:CONSOLE instead of /SUBSYSTEM:WINDOWS makes it work, but also opens the console window when launched.
4. This is not the case when running on the phone emulator. The release build opens fine there.

Have you tried running Process Monitor to understand what might be happening?

Just to add a few more info from my experience: my game always crashes at a particular point in the UWP build (no crash in other platforms), both with release and release_debug, but NOT with target=debug

@nunodonato that crash is something in the audio server. I am not sure if it's related to the server itself or my xaudio driver implementation. And I don't know why it does not crash in debug builds.

@vnen I've been away for a while. Was there any significant changes done recently that could have improved this?

[vnen]

@nunodonato no, I don't think so. I'll have time to investigate next week.

This is from the recent Godot 3.0 Beta 2:

Not sure if this is any help but I've was able to figure out to export a game project to UWP, so I've tried to export a 3D model with a texture to UWP. However, as you mentioned in this issue, it crashes on Release mode. So I tried Debug and it was able to open fine but with a bit of a big issue:

The texture does not load on the sphere.(Its the Godot Icon PNG file I used to test)

The Debug output terminal also generated this Error message before the textureless sphere was displayed:

**ERROR**: Condition ' !is_inside_tree() ' is true. returned: Transform() At: scene\3d\spatial.cpp:265:Spatial::get_global_transform() - Condition ' !is_inside_tree() ' is true. returned: Transform()

Just figure I'd share what problems I've ran into, once again not sure if this helps at all.

P.S. The device I've used to test is the Wacom Cintiq Companion 2 by the way.

Any news on this bug? Is it already fixed on version 3?

[vnen]

No, I have no idea how to fix this. I guess I'll just set the release build to use SUBSYSTEM:CONSOLE an hope the console window doesn't get in the way. But UWP doesn't work with well the GLES3 renderer, so it will be limited to GLES2 once that's available. Until then I don't have plans to touch the platform.

Is there any workaround for this bug? This still does not work in 3.1-beta1...
