ios - iPhone相机启动时崩溃，错误很少但模糊

Question

我应该注意到这是一个增强现实项目。应用程序与 Mono2x 完美配合。更改为 IL2CPP，因为应用商店需要 64 位。启动画面仍在播放，但现在当相机尝试启动时，应用程序崩溃。

我正在实例化代表玩家得分的对象。这与 Mono2X 完美配合。我也有一个非常简单的碰撞，以前也很好用。

我得到这样的非常模糊的错误：

ArgumentException: The thing you want to instantiate is null.
at UnityEngine.AssetBundle.LoadAsset_Internal (System.String name,  
System.Type type) [0x00000] in <filename unknown>:0

(Filename: currently not available on il2cpp Line: -1)

我在加载 ARMarker 时也遇到错误。无论如何，标记成功加载。

ARController (native): [error]Loading single AR marker from buffer,   
width 55.000000.
ARController (native): [error]ARController::addMarker(): called
ARController (native): ARController::addMarker(): Added marker (UID=0), 
total markers loaded: 1, exiting, returning true
ARController: Starting AR.

我更关心导致程序崩溃的 ArgumentException。
