Cars - Chevrolet Corvette C8.R sound bug

From time to time the sound of the C8.R bugs out and it sounds like parts of the soundfile are missing or not loading correctely. I have checked and repaired my game files and restarted the game multiple times and tried to recreate it but there seems to be no exact trigger. It just happens randomly when racing on track no matter if singleplayer, multiplayer, pracitce, quali or race. Since its hard to recreate and it might not happen at all even after hours of racing I have no clip of it

I experienced the same problem in the C8 series in the 2nd race. When the accelerator is pressed the motor sounds and if you leave it there is dead silence from the motor although the revs are high. It was ok in the subsequent races.
