Mario Tennis Aces update version 2.0.1 was released earlier today, but players have already started to report a problematic issue with it.
Whenever you try to access the new online Co-op Challenge mode, the game will crash with the message: “The software was closed because an error occurred.”
Nintendo has stated that they are aware that the game is now crashing under these specific circumstances, and has promised to release a new software update to correct the problem on Tuesday 16th October.
In Co-op Challenge mode, players team up online to participate in time-limited missions. If you complete set objectives while these missions are active, you can unlock special outfits, characters with alternate colour schemes and more.
Mario Tennis Aces is now available exclusively for Nintendo Switch worldwide.
