why dbghelp.h's symbol related functions always return 126 error code?

Question

When i try to use the functions SymbolFromName() e SymbolFromAddress() the return code always return 126 (MODULE_NOT_FOUND), the code is :

    #include<dbghelp.h>
    #include <iostream>
    #include <Windows.h>
    #include <windows.h>
    #include <debugapi.h>
    #include <WinBase.h>
    
    using namespace std;

    int main(){
    DWORD  error;
    HANDLE hProcess;

    SymSetOptions(SYMOPT_UNDNAME | SYMOPT_DEFERRED_LOADS);

    hProcess = GetCurrentProcess();

    if (!SymInitialize(hProcess, NULL, TRUE))
    {
        // SymInitialize failed
        error = GetLastError();
        cout << "SymInitialize returned error " << error << endl;;
        return FALSE;
    }}
    

    hProcess = GetCurrentProcess();

    SymSetOptions(SYMOPT_UNDNAME | SYMOPT_DEFERRED_LOADS);
    SymInitialize(hProcess, NULL, TRUE);

    TCHAR szSymbolName[MAX_SYM_NAME];
    ULONG64 buffer[(sizeof(SYMBOL_INFOW) +
        MAX_SYM_NAME * sizeof(TCHAR) +
        sizeof(ULONG64) - 1) /
        sizeof(ULONG64)];
    PSYMBOL_INFO pSymbol = (PSYMBOL_INFO)buffer;

    _tcscpy_s(szSymbolName, MAX_SYM_NAME, TEXT("mainCRTStartup")); // i  
    know the entrypoint name by using >>nm command in windows for extract 
    symbol
    pSymbol->SizeOfStruct = sizeof(SYMBOL_INFO);
    pSymbol->MaxNameLen = MAX_SYM_NAME;

    if (SymFromName(hProcess, szSymbolName, pSymbol)){
       cout << pSybol->address
    } // this return always 126

    }

i use VisualStudio and the default debugger for testing it. Part of the code above is taken from MSDN documentation, here.

EDIT : i know the main simbol thanks to nm, that can extract a list of symbols, in my case it contains :

 00401300 T _WinMainCRTStartup
 00401460 T _main
 004012e0 T _mainCRTStartup

I also try to using different symbols name like main, mainCRTStartup, wWinMain, WinMain and so on, without any results
