我将项目更新为 .NET 8，将 Mac 更新为 MacOS 14 和 XCode 15。当我构建 MAUI iOS 项目时，它失败并显示以下构建日志：

我检查了 Windows 笔记本电脑上的文件夹，发现
C:/Program Files/dotnet/packs/Microsoft.NETCore.App.Runtime.Mono.ios-arm64/8.0.0/runtimes/ios-arm64/native/libmono-component-hot_reload-stub-static.a/Users/lukevo/Library/Caches/Xamarin我还尝试禁用热重载，因为我不使用它，但问题仍然发生。在尝试再次构建之前我也运行了
dotnet nuget locals all --clear新创建的具有捆绑签名设置的 MAUI Blazor Hybrid 也会发生这种情况（如果没有签名，则不会出现错误）。
请告诉我如何修复它或建议下一步诊断问题。
如果您的日志文件在任何 Mac 代理的“安装”、“上传”或“启动”步骤中显示问题，您可以尝试删除 XMA 缓存文件夹以强制 Visual Studio 重新上传它们。
如清除 Mac 上的 Broker、IDB、Build 和 Designer Agents 中所述，您可以尝试删除 Mac 和 Windows 上的 XMA 文件夹。 （本文档是关于 Xamarin 的，它也适用于 MAUI）。
对于 Macos，XMA 文件夹位于
"$HOME/Library/Caches/Xamarin/XMA"对于 Windows，XMA 文件夹位于
%localappdata%\Temp\Xamarin\XMA将它们都删除。下次启动时，Visual Studio 将检测并重新上传它们。删除文件夹后，重新启动 Visual Studio 和 Visual Studio for mac。
有关使用配对到 mac 时进行故障排除的更多信息，您还可以参阅Xamarin.iOS 构建主机的连接故障排除。
