ICU4C doesn't work in VSCode despite libraries being linked

Question

First of all ICU4C 72.1(latest version)

In continuation of my previous question i rewrote my code to use ICU, I dont want to use makefile for a time being. So I use Visual Studio Code compiler.

The problem is it doesn't seem to load libraires and I dont know why.

So those are my c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**",
                "${workspaceFolder}/icu-windows/include/**",
                "${workspaceFolder}/icu-windows/include"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "compilerPath": "C:/msys64/mingw64/bin/g++.exe",
            "cStandard": "c17",
            "cppStandard": "gnu++17",
            "intelliSenseMode": "windows-gcc-x64"
        }
    ],
    "version": 4
}

and tasks.json

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: g++.exe сборка активного файла",
            "command": "C:/msys64/mingw64/bin/g++.exe",
            "args": [
                "-fdiagnostics-color=always",
                "-IC:\\Users\\pasha\\Downloads\\NLP\\icu-windows\\include",
                "-LC:\\Users\\pasha\\Downloads\\NLP\\icu-windows\\lib64",
                "-g",
                "${file}",
                "-licuin",
                "-licuuc",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
                "-Wno-multichar"
            ],
            "options": {
                "cwd": "C:/msys64/mingw64/bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Created"
        }
    ],
    "version": "2.0.0"
}

whether

                "-licuin",
                "-licuuc",

are present or not i get this HUGE error message

UPD: The function

icu::UnicodeString normalise(icu::UnicodeString to_normalise)

        {'_', ' '},
        {'á', 'a'},

        {'â', 'a'},
        ...
    };

    // Create an output string
    icu::UnicodeString result;
    icu::StringCharacterIterator iter(to_normalise);
    // Loop over the input string
    for (UChar32 c = iter.first32(); c != icu::StringCharacterIterator::DONE; c = iter.next32())
    {
        // If the character is in the map, replace it
        if (char_map.count(c))
        {
            result += std::tolower(char_map[c]);
            continue;
        }
        else if (std::isalpha(c))
        {
            // If the character is alphabetic, add it to the output string in lowercase
            result += std::tolower(c);
            continue;
        }
        else if (std::ispunct(c) || myn::isemoji(c))
        {
            result += c;

    return result;
