No i found the solution
For PS4 users, this glitch only happens when you have a custom made player signed to your team at the time!
You have to either sell/release them in order to be able to play the next season, then you can resign them etc. But i think you'll have to sell/release them EVERY season!
Kinda stupid and i hope EA fix this (probably for old gen), but yeah you can still play career mode just you cant with custom generated players!
I have a situation where the Game crashes during the last match in champions league and i have a created player and the questions is whether i need to delete him so that i can finish season
