请问这个问题是什么意思啊？如何解决？

应当使用 XeLaTeX 编译，请详阅 README。

能否帮忙看下错误原因？非常感谢！

建议直接使用默认配置，也可能 tex 文件有其他部分的错误，建议检查一下 main.log，建议先 clean 再编译。使用 latexmk 是为了读取 .latexmkrc 中的配置，引导 TeX 程序正常识别 texmf 文件夹中的依赖文件，也可以尝试直接使用这种配置，即不添加参数：

      {
            "name": "latexmk_rconly",
            "command": "latexmk",
            "args": [
                "%DOC%"
            ],
            "env": {}
        },

破案了，是我的texlive2021版本太低，更新到2023就好了！
