Attach GDB to process freezes

I am trying to setup my launch.json in order to be able to debug my executable from another process. In this regard, I've defined the following configuration:

{ 
            "name": "(gdb) Attach",
            "type": "cppdbg",
            "request": "attach",
            "program": "D:\\c-tmp\\count.exe",
            "processId": "${command:pickProcess}",
            "miDebuggerPath": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-win32-seh-rt_v6-rev0\\mingw64\\bin\\gdb.exe",
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true,
                    "set follow-fork-mode":"child"
                }
            ]
        }

If I launch this config, I'm able to connect with the desired process, but whenever I am trying to launch the program, the debugged process will freeze until I stop the debugger.

I addition I cannot find my debug breakpoint activated on vscode side, though it is connected:

Can someone help me tweak my config properly?

Start with the launch.json configuration using the cppdbg attach request, processId picker, and GDB path, then reproduce the freeze when launching the attached program. Investigate why the process remains stopped and why breakpoints do not activate; done means attaching no longer freezes execution and the configured breakpoint becomes active.
