The trouble is that, when I start the game, the black screen is shown on a title screen, but a button to press to start a game or accessibility can be seen. Restarting the game didn't help.
I'm playing this game on Xbox Series X.
Yep I got the same problem too. UI elements are visible like text and subtitles but the actual graphics for the game is completely black. Hopefully a fix will happen soon enough.
I've experienced the same black screen. A couple of restarts ended with the same results.
Next I Loaded Forza Motorsports 7 and was successful to play that game for a moment.
RESTARTED my Xbox Series X.
Reloaded Forza Horizon 4 and I was welcomed back by Anna.
Enjoying gameplay now.
