Remove XMRig window when using embedded config.
I was making a custom build of XMRig with VS and I was wondering if it is possible to remove the window that says this:

I can remove the actual error codes by removing this part of code:
```
bool xmrig::JsonChain::addFile(const char *fileName)
{
    using namespace rapidjson;
    Document doc;
    if (Json::get(fileName, doc)) {
        m_fileName = fileName;

        return add(std::move(doc));
    }

    if (doc.HasParseError()) {
        const size_t offset = doc.GetErrorOffset();

        size_t line = 0;
        size_t pos  = 0;
        std::vector<std::string> s;

        if (Json::convertOffset(fileName, offset, line, pos, s)) {
            for (const auto& t : s) {
                LOG_ERR("%s", t.c_str());
            }

            std::string t;
            if (pos > 0) {
                t.assign(pos - 1, ' ');
            }
            t += '^';
            LOG_ERR("%s", t.c_str());

            LOG_ERR("%s<line:%zu, position:%zu>: \"%s\"", fileName, line, pos, GetParseError_En(doc.GetParseError()));
        }
        else {
            LOG_ERR("%s<offset:%zu>: \"%s\"", fileName, offset, GetParseError_En(doc.GetParseError()));
        }
    }
    else {
        LOG_ERR("unable to open \"%s\".", fileName);
    }

    return false;
}
```

But I can't actually remove the window that opens.

Thanks in advance!
