C++ bit7z Unresolved External Symbol _imp_CharUpperW#4 - c++

Question

I'm trying to use bit7z in my C++ code to create a program that zips a directory. I'm receiving a LNK2019 error for something called _imp_CharUpperW#4 in my bit7z_d.lib. My IDE is Visual Studio Community 2019 and I use C++ 20.
These are my files:
main.cpp
#include <QCoreApplication>
#include <string>
#include <iostream>
#include <filesystem>
#include <bit7z.hpp>
#include "main.h"
#include <bitcompressor.hpp>
namespace fs = std::filesystem;
using namespace bit7z;
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
std::string path = "C:/Users/aretz/Downloads/test";
for (const auto& entry : fs::directory_iterator(path))
std::cout << entry.path() << std::endl;
return a.exec();
}
void AIXLogger::CompressDir() {
Bit7zLibrary lib{ L"C:/Program Files/7-Zip/7z.dll" };
BitCompressor compressor{ lib, BitFormat::Zip };
vector< wstring > files = { L"C:/Users/aretz/Downloads/test" };
wstring zip = { L"output_archive.zip" };
compressor.compressFiles( files , zip );
}
void AIXLogger::Execute() {
CompressDir();
}
main.h
#pragma once
#include <qwidget.h>
#include <qobject.h>
#include <bit7z.hpp>
class AIXLogger : public QWidget
{
Q_OBJECT
public slots:
public:
void CompressDir();
void Execute();
};
