[xvly]

I also met this crash!

[watsonsong]

I found the crash will happend in editor as the same.
I attach the crash dump and the editor log.
The log is the same with android:

I found some one maybe met the same problem:

Unity IssueTracker - Disabling UI crashes at GameObject::IsActive

And I think the Destroy Canvas cause this problem, so I delay the Destroy by adding 0.1 second.
GameObject.Destroy(uiroot, 0.1)

The crash stack become this:

[watsonsong]

I found the crash cause by Destroy the Canvas and GraphicRaycaster component. It may cause crash on both android device and editor.
Is there any one met the same problem.

[Menion-Leah]

Same problem here!
I also posted there:

Hard crash when enabling/disabling UI elements

It happens a lot in Unity 2017.2 and 2017.3.0p1. I wasted weeks trying to get rid of this random crashes, both in editor and Android builds. Basically, if you quickly click over UI elements that activate/deactivate others, or when you quit the game, you get an hard crash, both in editor and Android builds, with vague (or zero) information logged. A typical stack trace shows this (Android): [quote] Thread 0 (crashed) 0 . 1 Mono Runtime at (wrapper managed-to-native) UnityEngine.GameObje…
