Cleared cache and I think I already turned off music, but I'm not sure. I can find my music library, but I cannot find the setting that let's me turn on/off custom music. Can someone point me in the right direction?
BTW, clearing the cache makes not difference. I can also confirm the issue is not just with seasonal events. I was racing online in a room a friend of mine created last night via the Open Lobby. After racing a while I backed out to cancel my entry and switch cars. As soon as I tried to cancel the race, the system locked up again. I could see the lobby of the room, but the selection pointer was nowhere to be found, and I was basically locked-up (again). Had to do another hard restart.
I'm about to bail on Gran Turismo for good. GT4 was buggy and GT5 isn't much better. Features, tracks, cars, etc. don't mean diddly if you can't seamlessly play the game without worrying about loss of data or system crashes.
