【问题描述】：
我正在开发一个 Outlook 加载项应用程序，发现自己无法在本地运行它，尝试在“Office 桌面客户端”中运行它时出现以下消息：
“加载项错误，内容被阻止，因为它没有由有效的安全证书签名”
当我尝试使用 Chrome 或 Edge 运行插件时，我在插件中收到以下消息：
“加载项错误：出现问题，我们无法启动此加载项。请稍后重试或联系您的系统管理员。”
如果我尝试在 Chrome 或 Edge 上点击“重试”，我会收到以下加载项错误：
“此插件可能无法正常加载，但您仍可以尝试启动它。”
当我点击开始时，我得到以下信息：
“位于 https://localhost:44364/AddinClient?et=#/read 的网页可能暂时关闭，或者它可能已永久移动到新网址。”
当尝试在新标签页中通过 chrome 手动访问此地址时，它会设法在“此站点注意安全”警告之后加载到该标签页中
我注意到此问题的一些常见修复方法，例如在 Internet 选项中将 localhost 添加到受信任的站点并安装 office-addin-dev-certs，但是这些选项都没有解决问题（我也尝试过删除并重新- 安装我见过多次出现的证书）。
还有什么我可以尝试的吗？
有关我的设置的一些技术细节，我使用的是 Microsoft® Outlook® for Microsoft 365 MSO（版本 2110 Build 16.0.14527.20270）64 位。我使用的是 Windows 10 Pro，插件的清单文件如下：
