I want to debug my code, so I add __debugbreak(); at the line that I want to break, then I build and run my program, then the windbg is invoked as expected(I had set up windbg properly in regedit, so that the __debugbreak() will make windbg attach my program). But, windbg can't stop the program at the line that I add __debugbreak(); but BUSY(Debuggee is running...) like below: What's the problem? How can I deal with it?

The last output in the command window is:

Microsoft (R) Windows Debugger Version 10.0.22473.1005 AMD64
