问 flutter_build - FileSystemException:创建Flutter失败，权限被拒绝

我正在尝试运行我的Flutter应用程序。它以前工作得很好，我不知道发生了什么，但现在它就是不能启动。

当我尝试从Android Studio启动它时，我得到：

Crash report sent (report ID: [crash id])
Oops; flutter has exited unexpectedly.
Crash report written to /home/my_project_path/flutter_07.log;
please let us know at https://github.com/flutter/flutter/issues.

当我尝试用 flutter run 启动它时，我得到了同样的结果。

flutter doctor 运行得很好，我没有得到任何错误：
