Help (Old Glitch)

I was playing Forza Horizon 3 on my new xbox series x and i was trying to get 3 stars on a pr stunt when then i keep hitting the rewind 5-8 times trying to get the stunt perfectly to level up my festival when all of the radio and car sounds stopped working the only things i can hear is the voices and crash noises i tried searching it up but there was nothing there about it seems that it was something unpatched from 2016 that was never fixed and i need help trying to fix it
