My compare files utility from Android Studio 2.3.3 is not working anymore, it shows the message "Can not calculate diff" and generate the following error on Event Log:
NullPointerException: update failed for ActionGroup: null (null)[null]
Here is the log captured by the Report to Google dialog
I'm using Mac, I already uninstalled Android Studio, Android-sdk, cloned the project again from git and deleted the Android folder under ~/User/MyUser/Library/Android, but the problem continues.
It does not happen with the other computers from my team.
Anyone knows how to fix this? It wasn't happening last week.
