本地部署Project Server 2019：CSOM项目更新队列作业抛CommunicationObjectAbortedException

我编写了一段使用CSOM修改项目的代码，功能为更新项目所有者、添加新任务并分配资源，代码如下：

projContext.Load(this.projContext.Projects, pj => pj.Where(p => p.Id == projId));
projContext.ExecuteQuery();

var proj = projContext.Projects.SingleOrDefault(p => p.Id == projId);
var draft = proj.CheckOut();

projContext.Load(draft, p => p.Owner);
projContext.ExecuteQuery();

draft.Owner = managerUser;

var tasks = draft.Tasks;
projContext.Load(tasks, tsk => tsk.IncludeWithDefaultProperties(t => t.Id, t => t.StatusManager));
projContext.ExecuteQuery();

var newTaskId = Guid.NewGuid();
var newTask = new PS.TaskCreationInformation {
    Id = Guid.NewGuid(),
    Name = "New task",
    StatusManager = managerUser,
};
tasks.Add(newTask);
draft.Assignments.Add(new PS.AssignmentCreationInformation {
    TaskId = newTaskId,
    ResourceId = managerId,
});

var qJob = draft.Update();
var jobState = projContext.WaitForQueue(qJob, TimeoutSeconds);

这段代码在开发环境运行正常，但在生产环境中，针对特定类型的项目执行时，更新队列作业会失败并抛出内部异常。受影响的项目类型包括：

• 在PWA中新建的企业项目
• 通过Project Professional将本地项目导入服务器创建的企业项目

队列错误信息 #

您的项目更新作业已失败。当前状态为失败，完成度为0%，进入队列时间为2022年12月8日16:24:05。错误ID：9133、26000

以下是详细错误信息，请发送给管理员以进行更详细的故障排除。

您可以执行以下操作：

1. 使用错误ID和错误XML进行故障排除；
2. 将您的作业ID（db6df25a-d4c1-4631-b7a1-2e7aae9f5c16）和错误XML发送给管理员。

我尝试在开发环境复现该问题但未成功，推测问题由微软产品本身导致，寻求可行的绕过方案或解决办法。
