I've been getting an error (error 21) after I finish qualifying sessions, while I was searching for it, on Google's recommendations it appeared after finishing the race, I guess this happens after finishing sessions, the only options are go back and quit to desktop, go back does nothing so I have to close the game, I went back and it happened again, if anyone knows why this is happening and how to fix it I'd be very thankful because it's disappointing to put my time into something and then it just vanishing.
