【问题描述】：
如果我从头开始创建一个新项目或打开我以前的项目之一，我会得到：
java.io.FileNotFoundException: C:\Users\Terry.AndroidStudio2.2\system\android-palette\v1\layout_palette.xml （访问被拒绝）。
我以前没有任何问题，现在突然出现这个错误。
我使用 IDE 打开这个文件没有问题，所以我不明白为什么打开它有问题。
有人有什么建议吗？ 我使用的是 2.2.3 版本。
这是事件的顺序：
java.io.FileNotFoundException: C:\Users\Terry\.AndroidStudio2.2\system\android-palette\v1\layout_palette.xml (Access is denied)
