.NET 6 Isolated Azure Functions部署后Timer Trigger不触发求助

最近将Azure Functions项目切换为.NET 6 Isolated运行时，本地运行正常，但部署到Azure后Timer Trigger始终无法触发。已查阅相关帖子并尝试修改，问题仍未解决。以下是项目相关配置及日志信息：

Program.cs #

using Microsoft.Extensions.Hosting;

var host = new HostBuilder()
    .ConfigureFunctionsWorkerDefaults()
    .Build();

host.Run();

函数代码 #

using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.Logging;

namespace MyProj.AzureFunctions
{
    public class Functions
    {
        private readonly ILogger _logger;

        public Functions(ILoggerFactory loggerFactory)
        {
            _logger = loggerFactory.CreateLogger<Functions>();
        }

        [Function("Health")]
        public void Health([TimerTrigger("* * * * *")] MyInfo myTimer, ILogger log)
        {
            log.LogInformation("Health Check Successful.");
        }
    }

    public class MyInfo
    {
        public MyScheduleStatus ScheduleStatus { get; set; }

        public bool IsPastDue { get; set; }
    }

    public class MyScheduleStatus
    {
        public DateTime Last { get; set; }

        public DateTime Next { get; set; }

        public DateTime LastUpdated { get; set; }
    }
}

host.json配置 #

    "logging": {
        "applicationInsights": {
            "samplingExcludedTypes": "Request",

                "isEnabled": true
            }
        }
    }
}

local.settings.json配置 #

    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "AzureWebJobsDashboard": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated"
  }
}

.csproj配置 #

查看/LogFiles/Application/Functions/Host下的日志文件，未找到函数触发记录，仅重复记录主机运行状态：
