Hi guys, as a temporary fix to this problem I suggest that if you are using any of the DLC helmets or race suits to remove them and apply only base game items. I was using the gold Schumacher suit and kept getting the black screen, then booted back to the Xbox one home screen. As soon as I changed suits my issue was fixed. Played the next race and the game was working fine. Hope this helps, this issue will most likely be fixed soon enough.
(Please note, I have also submitted this as a separate bug report a few days ago. Just wanted to reply with some help for anyone still struggling)
Best regards.
