You say you are investigating the TT issue, are you investigating the podium pass/item shop crash issue that is resulting in the same error code? I have taken the steps that Sony has suggested (delete game/save files and initialise PS4) but unfortunately the game is still crashing.
Thank you for being so active and vocal in the forums - I know this can't be an easy time right now
edit: seen a few other people having the issue on xbox/pc so even though the error code is a standard ps4/sony one I believe the error is with the game, hopefully a patch can fix this quickly!
