On Lap 6 the textures on turn 1 and turn 7 were missing, after lap 11 the whole track disappeared, instead of the track I could only see the skybox and the breaking line.

I’m on Xbox, and Maple Valley consistently has this issue for me. Some races it locks up the xbox, booting to dashboard
On the PC this problem appears on lots of tracks, maybe all of them. It happens after you have been playing a while. In my case if I restart the game then the problem goes away so at the first sign of texture issues I look for the next available chance to restart the game and that works fine. If you keep playing long enough after the textures start dropping out it will crash.
I would advise that if you are about to start a race that will take more than 30 minutes to complete and have already been racing for a while that you should restart the game before starting the race.
