Death triangle and exclamation mark in front of orange car on display and p0a75

Hi guys, I had an accident a few days ago where came too fast off the highway (realized it was my stop too late) and drifted past the on/off road till I smashed my driver door against a concrete post . I drove my car to class after that and drove home 75km (50mi) around 5 hours later. I thought I got lucky in that the car still ran, but the next day when I turned the car on, I got the death triangle on the heads up display and an orange square on the upper left of the touch screen with an exclamation mark in front of a car on the touch screen. And while the car runs in hybrid-only mode, the engine won't start. My obd sensor showed error code P0a75 (and p0138, but i don't think that's directly relevant) which is described as "Generator Phase W Current has been detected".

Does anyone have any ideas of what could be causing the problem and what I might do to fix it? Or any tests i can do with a multimeter to narrow down my problem source?
I saw another thread here which dealt with the same death triangle and exclamation in front of car symbols ( Exclamation Mark , problem , no error messages | Page 2 | PriusChat ) and there was a loose wire. I'm guessing maybe when i tried open the front door after i got home i pulled a wire somewhere maybe? The HV seems to be working since it moves the car.

Thanks all!
(pics of everything i mentioned and the pic on right show how the door doesn't close properly at the top)
