Great! Guess I'm learning something new as well. Can you please send a screenshot of the error screen you were able to get? I could use it to infer what exactly the problem was. Make sure there's no personal info on there before you send it!
On another note, you shouldn't have random developer options toggled on all the time. I'd recommend you to first make screenshots of all the settings and then turn developer mode off, that should reset everything. And if you're in the mood for science, you can compare the default settings to your screenshots to figure out which setting did it.
