Driving video game lover

This game is awesome, I love the cars, and especially all the worlds you can drive in. I have had the game for 4 years. But, there has been a problem in the game every time I try to play a career lesson or single player, it loads, then the game crashes. The other problem is that after some updates, it’s extremely glitchy and almost can’t be played sometimes. I love this game so much and I hope it can be fixed.
