"CString not terminated" when using LLDB-MI with Visual Studio Code on Windows ARM64

I recently switched to an ARM64 machine with the Snapdragon X Elite on Windows and I am trying to set up Visual Studio Code. Since MinGW-w64 with gcc and gdb isn’t available for ARM64, I’m using LLVM-Mingw (version 18.1.18).(I also tried MSVC but I just cannot get used to it).

The problem arises when I try to start lldb-mi from within VS Code. I encounter the following error (full output at the bottom of the question):

[Error] MI parsing error: CString not terminated: ""C:\Users\User_\Documents\Development\TestProject"
[Error] MI parsing error: Result expected: "path="C:\Users\User_\Documents\Development\TestProject"
[Error] MI parsing error: trailing chars: ""C:\Users\User_\Documents\Development\TestProject"

The Launch Configuration (launch.json):

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(lldb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${command:cmake.launchTargetPath}",
            "showDisplayString": true,
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "logging": {
                "engineLogging": true
            },
            "externalConsole": true,
            "MIMode": "lldb"
        }
    ]
}

Debugging using only lldb directly via CLI works fine.
I also tried the vs code extension CodeLLDB but unfortunately that one is not available on ARM64 yet.

For anyone who would like to reproduce the problem.
The code is a simple Hello World program in C++ and CMake used:

cmake_minimum_required(VERSION 3.27)
project(TestProject)
set(CMAKE_BUILD_TYPE Debug)

add_executable(testProject ${CMAKE_CURRENT_SOURCE_DIR}/main.cpp)

target_link_libraries(  testProject)

Environment:

• Visual Studio Code version: 1.91.0 (user setup)
• Clang revision: 3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff
• LLVM revision: 3b5b5c1ec4a3095ab096dd780e84d7ab81f3d7ff

Any idea what I am missing?

Update based on Electro Organic’s suggestion:

I updated the launch.json with absolute path. I also move it into a path without an underscore, same issue persist. I also tried forward and double backwards slash, no change.
I checked with notepad++ for any hidden symbols but couldn’t find one either.

New launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(lldb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "C:\Users\Public\TestProject\build\testProject.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "C:\Users\Public\TestProject",
            "logging": {
                "engineLogging": true
            },
            "externalConsole": false,
            "MIMode": "lldb",
            "miDebuggerPath": "C:\BuildTools\llvm-mingw-20240619-ucrt-aarch64\bin\lldb-mi.exe"
        }
    ]
}
