Application crashs when I'm using UI in Unity5.0.1

Android and WP8 apps crash on launch, when I’m using canvas renderer. May be I’m losing something. Or I must recreate all scenes in 4.6.5 where canvas works?

I have check all other methods and I see that empty scene with only canvas renderer crashes too. Is it a bug?

In the Unity editor, go into Edit > Project Settings > Graphics and under “Always Included Shaders” make sure that it contains UI/Default and UI/Default Font.

If it doesn’t, add them. If it does, then I do not know what is causing your issue.
