Forza 7 XBox One X Crash

Currently doing:

Masters Championship
Classic Street Muscle

Using:
1968 Monaro GTS 327

Race # 5
Yas Marina Circuit

Every time I try to tune my car, when I hit apply, the game crashes. Sound glitches & stays on like a constant skip & the game locks up.
If I leave it, after a few seconds, it goes back out to Xbox Home screen and I have to start the game again.
Hard reset the console.
Still does it.
Chose to race without going to the tuning menu & was able to complete the race.

On the next race, I was able to tune my car, then complete the race, watch the replay, take a couple of photos, share them, then when I got out of the replay & went to continue, the game got stuck on a loading screen.
