Error deleting Google account from Samsung Galaxy S4

I recently upgraded my Samsung Galaxy S4 to Android Lollipop (5.0.01). I created a new Google account and then added it to the device; when I triee to delete the old Google Account from the device I didn’t succeed to access to the google account. I went into settings>accounts>google account, and an error popped up: "Unfortunately, Settings has stopped." Is there any other way to delete the Google account from my phone? Thanks in advance.
