Sometimes i get a black screen when changing from race or leaving to the main menu. It once happened during a Cupra Race when it should go to race 2 the screen went black, i still could hear the music but the game freezes.
I had exactly the same issue couple of times last days. It happens only during online racing when leaving setup screen for main race menu. My idea is that it may be related to internet connection (in my opinion sudden connection drop may cause such a scenario).
"Mass-Multiplayer Online" games. Like World of Warcraft and stuff. I mean, R3E requires online connection because it loads/verifies data at some points, but it doesn't load everything constantly.
