************** JIT 调试 **************
要启用实时(JIT)调试，
该应用程序或计算机的 .config 文件(machine.config)的 system.windows.forms 节中必须设置
jitDebugging 值。
编译应用程序时还必须启用
调试。

例如:


    


启用 JIT 调试后，任何未经处理的异常
都将被发送到在此计算机上注册的 JIT 调试程序，
而不是由此对话框处理。

Hi @cm,

Thanks for sharing this issue. As to this issue, the Dev Team has said that

There is no specific timeline for when to solve all the issues for apps running as admin. We are trying to improve experience for apps running as admin and made a change recently in Edge 112 though.

It means that the Dev Team is working on this issue actively. You can test again on Edge 112 once it is released. If you have additional information to share, you can add comments on that GitHub post to help the Dev Team learn more about it.
