title: IDE Error when creating a new activity in android studio 3.0.1
body: <p>I am having problems to create new activities in Android Studios 3.0.1 for Windows 10, the issue is that until yesterday everything worked, but now it throws errors when trying to create a new activity and then, do not create it.</p>
  
  <p>Only create classes, or empty activities, but no other that appears in the gallery.</p>
  
  <p>The error message is:</p>
  
  <blockquote>
    <p>Inconsistent FILE tree in SingleRootFileViewProvider{myVirtualFile=LightVirtualFile: \targetFile, content=VirtualFileContent{size=69}}; nodeLength=137; fileLength=69</p>

  <p>I've done everything, I've downloaded the latest version of gradle and I've reinstalled Android Studio, several times.</p>
