Game lost

I was playing my Forza Horizon 3 game which auto saved as I played and I was able to pick up where I left off every time until today. Today when I turned on the game to play, everything had been lost and looks like I will have to start all over again. Do you know if it is saved somewhere that I can retrieve it again before I start again. This is so frustrating.

Probably should have posted in the Support section
There is also a sticked thread at the top of that section especially for your issue with instructions what to do
