Low Streaming Bandwidth at the start of the race.

Hello! I have a i5 7600, gtx 1066 6gb and 16gb of ddr4 ram. The game is running perfectly on my PC and I never had any problems with it. Today, I tried playing my first ranked match in the new Solo Ranked Adventure (Free-for-all) and, at the start of the race the the whole environment dissappeared and I got this message: http://prntscr.com/m8140r
Then, I got teleported on a track that I played on (custom made) before the ranked adventure. http://prntscr.com/m814f0
Now, I’m afraid not to get a lower rank that I needed to get (because I restarted the game after this problem occured) and I’m also worried that the problem may occur again.
BTW I never had a problem like this with the game.
