Unable to launch debugger

### Brief Issue Summary

Launching debugger for the selected target does not work. After multiple reloads of VS Code it will eventually work. There is no issue building or launching the target, only when debugging.

I am connected to a docker container through VS Code.

### CMake Tools Diagnostics

```shell
{
"os": "linux",
"vscodeVersion": "1.95.3",
"cmtVersion": "1.20.30",
"configurations": [
{
"folder": "/workarea",
"cmakeVersion": "3.31.0",
"configured": true,
"generator": "Ninja",
"usesPresets": false,
"compilers": {

"CXX": "/opt/bb/bin/g++"
}
}
],

},
"settings": [

"configureOnOpen": false
}
]
}
```

### Debug Log

```shell
When trying to launch the debugger:
[extension] [1222] cmake.debugTarget finished (returned undefined)

Possibly related, when trying to set the build target:
[extension] [2831] cmake.setDefaultTarget finished (returned undefined)
```

### Additional Information

Selecting the launch target does not have the same issue:
```
[extension] [3327] cmake.selectLaunchTarget finished (returned "/home/nobody/buildarea/___/___.exe")
```

_No response_

Start by tracing the cmake.debugTarget and cmake.setDefaultTarget operations, using the CMake Tools Diagnostics and debug log in the issue as the initial reproduction context. Compare them with the successful cmake.selectLaunchTarget operation in a VS Code-connected Docker container. Done means the selected target can consistently launch under the debugger without reloads.
