INABILITY TO PROCEED TO THE NEXT SEASON AFTER A PLAYER RETIRES IN HIS CAREER

I opened a player career and played with the player I created for 15 seasons, then I decided to retire and had my jubilee. Then I wanted to go to another team and continue coaching, so I went to Aston Villa. I finished the season while I was the coach of Aston Villa and at the end of the season it was my second time as coach. I clicked on the end of season button to switch to the next season, but when I clicked on the end of season button, it always throws me back to the main menu and I cannot manage the character I worked so hard for.
