问题描述
我在我尝试为 Hololens 2 开发的应用程序的场景中添加了一些 MRTK 工具箱按钮，但这些按钮始终为粉红色。不过它们是可点击的。
这些是我安装的插件：
为了让它们工作而尝试的事情（我总是导入建议的 Textmesh Pro 文件）：
- 切换构建平台
- 启用所有 Windows 混合现实平台功能
- 尝试在 Unity 2019.4.24f1 和 Unity 2020.3.1f1 上创建新项目
- 已删除库文件夹
我觉得这可能是我没有设置的设置，但我很缺乏经验。我还能做进一步的故障排除吗？
附录：我在控制台中有一条无法消除的错误消息。 （即使在新创建的项目中它仍然存在）：
