After qtp is started using the plug-in ActiveX plug-in, ie cannot be started.

I encountered a problem today: After qtp is started using the plug-in ActiveX plug-in, ie cannot be started, But the strange thing is that I used the plug-in yesterday and it was okay this morning, because I have been checking the information while I open qtp, and I am also using ActiveX, So I accidentally closed the webpage, and the problem arises, I use a window browser, but if I use IE6 in the system, there is a solution: close all the 360 software and exit completely, after qtp is started using the plug-in ActiveX plug-in, enable the system's built-in IE6. The problem is fixed;

But now it's strange that the window of the world cannot be started with this method ....
