Visual studio 2015 VS 2015（社区）设计器崩溃，FileNotFoundException

我刚刚在windows 10 HP pc（从windows 8.1更新）中安装了visual studio 2015社区版。问题是设计器无法加载

这就是我得到的错误

我在网上搜索过，但运气不好。我没见过有人有这种例外。 我见过一些人有NullReferenceException及其解决方案。但找不到具有FileNotFound的用户

编辑：重新安装解决了问题

我会尝试修复visual studio 2015，看看它是否安装了丢失的文件。@KenTucker感谢您的评论。我试着把它修好，但没用。我将尝试一起重新安装
