Exception has occurred-Interrupt when add breakpoint to beak the program in attach request on extended-remote target

Environment

• OS and version: Ubuntu 20.04
• VS Code:1.74.2
• C/C++ extension: v1.13.9
• OS and version of remote machine (if applicable):
• GDB / LLDB version: gdb 9.2

Bug Summary and Steps to Reproduce

Bug Summary:

Steps to reproduce:

1. Source code
   #include <stdio.h>

   int main()
   {
   while(1){
   sleep(5);
   printf("\n\nHello world\n\n");
   }

      return 0;
   

   }

build it with -g to a.out.

1. Run it on remote target, and launch gdbserver "gdbserver --multi :23456"
2. Create attach configuration on localhost VScode to attach it.
3. No breakpoint set，run the attach and select the process id of a.out, it works well.
4. Try to set BP on line "sleep (5)", exception occured.

Reproduce the attach scenario from the provided configuration using gdbserver in extended-remote mode, then set a breakpoint on the sleep(5) line. Start with the debugger logs around AD7ExceptionEvent and the stopped event, and use the absence of an unexpected Interrupt exception after setting the breakpoint as the completion check.
