Main System Crash Issues PLS HELP DESPERATE

[Reese]

I have been fighting this same system crash issue for various different characters. I have concluded that its due to new characters being created but this most recent time i uninstalled New Beginnings because it was clashing with some race mods i had installed and that seemed to fix the issue. I was able to log in and out a couple times and it worked fine until now it crashes me like before. When i load up the game everything is fine until i try to load my characters and thats when i am given the message. Any help on this besides deleting the character would be heavily appreciated. (Deleting the character does work but i dont really want to delete my characters all the time)
