HarmonyOS 鸿蒙Next DevEco预览器崩溃并无法恢复，可稳定复现
在退出DevEco的时候，previewer就会崩溃并无法再启动，导致再打开DevEco后预览器会报错 No port is available from the preconfigured port range. Close all other apps and restart the Previewer.
尝试重启DevEco无效，只有重启电脑才行，但是我不可能关一次DevEco就重启一次电脑吧？
DevEco版本：DevEco Studio 3.1.1 Release Build Version: 3.1.0.501, built on June 20, 2023
previewer版本：3.2.3.6
操作系统版本：macOS 14.3.1 (23D60)，MacBook Pro 2019
如下为previewer.log中的崩溃信息：

在预览报错之后，预览器的后端进程也会崩溃。观察到是Previewer进程退出导致的。
提前抓到了Previewer的启动命令，在崩溃后尝试手动运行，但是在打印出日志 “[INFO][RichPreviewer.cpp][NotifyInspectorChanged][107][2024-02-14T16:27:52.580]:Send inspector json tree.” 后卡死，ctrl-c也不响应退出。
在关闭DevEco再重新打开之后，发现Previewer和openharmony-preview-server/index.js进程全没了，预览器也不再正常工作，只有重启电脑。
附抓到的启动命令：

HarmonyOS鸿蒙Next DevEco预览器崩溃并无法恢复的问题可能与以下几个因素有关：
-
系统兼容性：预览器可能未完全适配当前操作系统版本，导致崩溃。
-
资源占用过高：预览器在处理复杂UI或大量数据时，可能因内存或CPU资源不足而崩溃。
-
软件缺陷：预览器本身可能存在未被发现的bug，导致在特定操作或场景下崩溃。
-
依赖项冲突：预览器依赖的某些库或组件可能与其他已安装的软件冲突，导致崩溃。
-
缓存或配置问题：预览器的缓存文件或配置文件损坏，可能导致崩溃且无法恢复。
-
硬件问题：设备硬件性能不足或存在故障，也可能导致预览器崩溃。
-
网络问题：预览器在加载远程资源时，网络不稳定或超时可能导致崩溃。
-
第三方插件：安装的第三方插件可能与预览器不兼容，导致崩溃。
-
多任务处理：在同时运行多个任务时，系统资源分配不均可能导致预览器崩溃。
-
日志分析：通过查看系统日志或预览器的错误日志，可以进一步定位崩溃原因。
建议检查以上可能的原因，并根据具体情况采取相应措施。
