IL2CPP error on Building for Windows
Workaround for building with IL2CPP with Visual Studio 2022 17.4

参考的文章

方法一：修改环境变量（我的电脑 -> 属性 -> 环境变量）
变量名: _CL_
变量值: /D_SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS

方法二：Unity新建脚本，复制粘贴下列代码，打包即可。

#if UNITY_EDITOR
using System;
using UnityEditor.Build;
using UnityEditor.Build.Reporting;
public class MsvcStdextWorkaround : IPreprocessBuildWithReport
{
    const string kWorkaroundFlag = "/D_SILENCE_STDEXT_HASH_DEPRECATION_WARNINGS";
    public int callbackOrder => 0;
    public void OnPreprocessBuild(BuildReport report)
    {
        var clEnv = Environment.GetEnvironmentVariable("_CL_");
        if (string.IsNullOrEmpty(clEnv))
        {
            Environment.SetEnvironmentVariable("_CL_", kWorkaroundFlag);
        }
        else if (!clEnv.Contains(kWorkaroundFlag))
        {
            clEnv += " " + kWorkaroundFlag;
            Environment.SetEnvironmentVariable("_CL_", clEnv);
        }
    }
}
#endif // UNITY_EDITOR
