我在启动文件>项目结构时遇到了这个问题。每次我尝试时，都会被告知以下内容：
3:40:36 PM NullPointerException: null 3:40:47 PM Throwable: module editors was not disposed 3:40:49 PM Throwable: module editors was not disposed (on second try)
显然，第一个问题是由于 Android Support 插件中的异常，第二个和第三个问题是由于 Android Studio 核心中的异常。有谁知道这意味着什么以及我该如何解决？
编辑：这些是问题的详细信息：
