If you are using the PC and have some mods added try playing around with the selected mods that are on as one of them may need updating since last time you played or one isn't compatible with the others or maybe one mod wasn't saved properly in the game, what might be an idea is to remove them all then re add them.
For the xbox it may be the DLC hasn't loaded properly and there for can't load it. have you tried uninstalling and re installing the DLC (for PC as well)?
also with the xbox you could also try clearing the game cache by holding the LEFT Bumper, RIGHT Bumper, and the X button all at the same time on the Xbox 360 controller as a game is launching. Once you get to the Main Menu or Title Screen of the game, you can let go of the buttons. There will be no notification to you that this process has completed because it is all done passively.
not sure for the Play Station sorry if this is what you're on. the xbox fix might be similar.
I'm on pc and yes I have played around with modding a lot, secondly it's all up to date since it started happening right after the time I used the command /showracemenu after that the game started messing up and closing etc
I have tried disabling all mods still had the problem but the mods worked on a new game I have also tried doing a full reinstall of the game and it seems to be only affecting this character's play through save
So this in mind do u think the save is broken and corrupted thus causing me to start over again?
