Technical issues (Gran Turismo 7)

Hello everyone, I'll be the first. In general, the game has a couple of problems at the moment for me.

The first music in the game plays in a strange way, in the menu they play 50/50 and never play in the race itself, a lot of settings flowed, but during the race I never heard a single track.

Second, I got to pickup truck races, but I don’t have a pickup truck, you can’t buy it and win too, what to do ?! Or did I miss something?

Forgot to specify PS5 prefix
