Create a Team Crashing

I was making a create a team for every state/province (on top of Vasy's Roster File). I've finished 34 teams but now when I try and create a new team the game crashes.

The players added to the team are not created players and it crashes no matter who i put on the team. Ive also deleted every team and then tried to create a new team and it still crashed.

Any Suggestions?

Ive uploaded the roster on Xbox -Franchise Expansion (Oct 22) by Vterion if you would like to help investigate.
