git checkout 分支后如何解决权限被拒绝错误？

Question

我正在从头开始学习 git 并遵循一些教程，但出现此错误：

 Yasser@pc MINGW64 ~/Documents/repos/Branching (Development)
 $ git checkout master
 Switched to branch 'master'
 Your branch is ahead of 'origin/master' by 1 commit.
   (use "git push" to publish your local commits)

 Yasser@pc MINGW64 ~/Documents/repos/Branching
 $ git st
 fatal: failed to stat 'C:/Users/toshiba/Documents/repos/Branching': Permission denied

 Yasser@pc MINGW64 ~/Documents/repos/Branching
 $ git branch
 fatal: failed to stat 'C:/Users/toshiba/Documents/repos/Branching': Permission denied

为什么在 git checkout 分支后出现这个错误 Permission denied 错误？
