Game Freezing and failing to save after 100 percent race distance/Long Play

I am playing F1 25 on the Xbox series S and after completing a 100 percent driver career race the game stutters from the podium screen, race highlights and fails to save the game. It either comes up with a fail to save message or gets stuck on the communicating with servers screen. This is very frustrating as I have just completed a full grand Prix this afternoon to experience the problem and had no option but to quit the game. When I restarted I discovered that I was taken back to the very start of the race so will have to complete the whole race again. I experienced this when completing back to practice sessions too, so it seems the game can't run for more then one hour before this occurs. This is a big problem. Please can this be looked at as a priority as this is a major issue spoiling my enjoyment. Are there any recommendations to stop this from happening?  Many thanks
