使用 MMC，我尝试远程管理 Hyper-V Server 2019 实例上的 Windows Defender 防火墙（无 GUI，仅 CLI）。NetBIOS 名称为SERVER1。
规则Windows Defender Firewall Remote Management已启用：

但是，当我单击“入站规则”节点时，MMC 崩溃：
虽然这没什么帮助，但是这是堆栈跟踪信息：
FX:{b05566ac-fe9c-4368-be02-7a4cbb7cbe11}

...这是应用程序事件日志条目：
正如预期的那样，安全和维护控制面板对此毫无用处。
当我从网络上的另一台机器尝试此操作时，MMC 不会崩溃——但入站/出站规则列表保持为空。那里没有生成任何相关的事件日志条目。
我该如何追踪并修复它，以便我可以远程管理服务器的防火墙？

我刚刚在另一台机器上遇到了 MMC 崩溃。
