Xbox game crashing after 2 to 3 online races

So since the latest update my game keeps crashing and quitting back to the xbox home page.

Track - All
Hopper - S & A class
Console - Xbox one x
When - After 2 to 3 races during the count down to next race. Worse when I try menu’s.

Game will play for ages on rivals etc. With no crash.

Xbox is on current omega release firmware.

Anyone else having this issue? I have not reinstalled as is digital download so don’t want to download 100gb if possible.

Its worse now happening after one race for a few races.

Have you tried a hard reset?

Everything bar deleting the game has been tried.

Well tried deleting the game and re downloading and still the same issue.
