'Project Structure' in Android Studio doesn't launch

Question

I'm having this issue launching the File>Project Structure. Everytime I try to I'm told the following:

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)

Apparently the first issue is due to an exception in the Android Support plugin and the second and third are due to an exception in the Android Studio core. Anybody know what this means and how I can solve it?

EDIT: These are the details of the issue:
