My game crashes every time I try to enter career mode

Same issue on Xbox Series S. I've completed year one of MyTeam, and on the Team Details screen after selecting the tracks to race for year two, I can't "confirm" any changes. If I change engine supplier, primary sponsor, or team name then click "Confirm" the entire game crashes. I did this trying different sponsors, tracks, suppliers, the same result.

Finally, I just said screw it and continued - same tracks, engine supplier, sponsor, and of course it worked.

In short, once you Enter MyTeam, don't hope to change any settings and actually grow you team - the game is too buggy to actually support that.
