我正在使用 Microsoft MRTK v2.0.3，并且正在尝试将空间感知添加到我的项目中，但是当我选择空间感知配置文件时，我不断收到以下错误：

Unable to register IMixedRealitySpatialAwarenessObserver service with a null concrete type.
UnityEngine.Debug:LogError(Object)

当我尝试在设备上进行模拟时，没有收集到有关周围环境的数据。我激活了空间感知和 VR 支持。

通过查看 MixedRealityToolkit 中的所有配置文件（GameObject 及其同名脚本），我解决了相同的问题（同类型的其他几个问题）。请注意指示无法找到某些组件的红色标记字段。

在此处输入图像描述

在这种特殊情况下，查看“Spatial Awareness”-Group 内部，复制现有配置文件并使用红色输入字段旁边的Try Fixing 。如果这不起作用，请手动搜索WindowsMixedRealitySpatialMeshObserver。

我希望这对你也有帮助。
