VS2022启动ASP.NET MVC应用时页面无法完成加载

问题概述 #

我有一个运行7年的ASP.NET MVC Web应用，1个月前完成并部署了基于Bootstrap 5模板的重大布局更新；昨日发布小更新后，生产服务器运行正常。今日准备进行其他更新时，本地开发环境无法正常加载页面：浏览器开始加载，标题已设置，但加载过程无法完成。单步调试layout.cshtml文件可完整执行完毕。

已排查操作 #

• 更换MS Edge和Chrome浏览器，问题未解决
• 切换Debug与Release配置，结果一致
• 无调试模式（Ctrl+F5）启动时，页面可正常加载

补充细节 #

1. 浏览器控制台无报错，页面已部分加载，加载指示器元素可见
2. 浏览器开发者工具网络面板显示有2个字体资源处于待加载状态
