为什么这段代码在C上会出现打开文件问题？

Question

我正在 macos macbook 上使用 vscode 进行编码。我在打开文件时遇到一些问题。
我不知道为什么不读取文件。文本文件位于同一目录中。但Unix可执行文件的结果是：

scheduling.txt
file open error: 2
Could not open data file: No such file or directory
zsh: abort      

文件目录

如你所见，名字没有问题。

    fclose(file);

我认为我正确编写了代码，但文件未打开

bruh 你在编写代码之前或之后保存了文件吗？
