Ok Ive run into this problem many times it has to do with something in the Cell of "Goodsprings" being corrupted so when you try to load into that cell it will crash your game everytime. Easy fix though. Simply wait 3 to 4 days, I always do 4 just to be safe, in a different cell. For example if you crash in Goodsprings do the wait in Primm (I think it works best if your inside a building too but idk if that matters). But all the wait does is resets the cells in your game for every location that you are currently not in. Everytime this has happened to me I have done this and it has worked 100% of the time. No need to start a new fresh game. I hope this helps.
