Forza Horizon 3 repeated issues

So this issue has happened for most of my play time of Forza - this isn’t a new thing. This is the first time it has severely affected me however. Whenever I play Forza, I pretty much always end my play session when it freezes and then crashes. This happens
pretty much every play session. I didn’t really care before, but now that I have been attempting to complete a 50 lap 10 hour Goliath race - and I get to 20 laps and then the game freezes and crashes - I find this to be a slightly more important issue. This
is the third time I have attempted this race, and I want to die now that I have completely wasted hours of play time. Freezing and crashing isn’t the only problem however, the game’s just generally buggy. Sometimes it slowly deteriorates, one feature disappears
at a time until the game fully crashes. The game has been deleted and reinstalled multiple times on both of my Xboxes, and this continues to happen on both, but only when I’m playing the game on my microsoft account. Also, the game is completely up to date
update wise. I am completely clueless and out of ideas. Any and all help would be appreciated.
