Crashed on All-Star weekend 3pt contest

Whenever i clicked into 3pt contest the system crashes

It's likely a problem with a patch you have installed. Try removing any updates you have installed that relate to All-Star Weekend mode (notably the court) as well as any players you've selected for the three point shootout. If that works, start replacing the patches one by one until the game crashes again so that you can pinpoint the update that is causing the problem. Once you've determined that, it might be possible to devise a solution that will allow you to keep all the patches without any issues.
