Crash on ios11 beta8 (DEBUG scheme)

Dear,

We've just encountered a bug on a iOS device running latest iOS 11 Beta in our app based on a "Custom Camera" sample.

We can reproduce the bug with the sample "Custom Camera" that comes within the SDK, by building it on XCode 9 beta, and launch it on a device running latest iOS 11 Beta in a Debug scheme (it works on Release).

Just after the calling [self.architectView start:^(WTArchitectStartupConfiguration *configuration) completion:^(BOOL isRunning, NSError *error) {}];] (with error with a nil value in completion), the app crashes on Thread "com.wikitude.sdk.render_queue", before displaying any images with the following log :
