The Nintendo Switch 2 has just released update 21.0.0, a patch that introduces Menu changes, new download options, GameChat improvements, and additional language support.
An ideal way to enjoy, in the best possible conditions, games such as the recent Pokémon Legends: ZA, or previous deliveries compatible with the new hybrid.
But this is exactly what many users are unable to do, due to a bug fixwhich is causing headaches in the Pokémon community.

Pokémon ZA Legends is a new installment in the subsaga that began with Pokémon Arceus Legends. Available for Nintendo Switch and Switch 2, this game offers a revamped combat system.
Patch 21.0.0 affects Pokémon Brilliant Diamond and Shining Pearl
As the system upgraded to version 21.0.0, several users started reporting bugs in Pokémon Brilliant Diamond and Shimmering Pearl.
Specifically, experience game crashes when performing soft resetsa very common practice among hunters of varying colors.
The “trick” is this: use quick resets to restart the game without progressingrepeating encounters with legendary Pokémon until you get a shiny one or one with better stats.
According to a statement from the user who opened the thread on Reddit, the bug appeared shortly after the update and manifests itself in Diamante Brillante, one out of eight times when restarting.
The issue does not affect gameplay during normal gameplay, but appears insistently when restarting itespecially in long sessions of searching for legendary Pokémon like Darkrai.
Other players replicated the error in Shimmering Pearlalthough less frequently, which suggests that the incidence may vary depending on the game version.
Switch 2 appears to be the platform where the issue is most easily reproducedwhile on the original Switch this almost doesn’t happen.
In the thread, some mention dozens of blocks during Uxie or Shaymin hunting dayswhile other lucky people claim to have experienced nothing similar.
The most widespread theory is that some internal adjustment –related to software handling or compatibility layer— would be generating these errors when starting the game.
A user claims to have received confirmation from Nintendo that Your report has been transferred and the company is investigating the case.
It is unclear whether the issue will be resolved through a new system patch or if it requires the intervention of the remake’s original developer, ILCA.
Meanwhile, the community is divided between those who take the risk of blockingand those who have decided to pause their games until Nintendo clarifies the situation.
Pokémon fans, who dedicate hours and hours to this game, I hope for a solution soon. Let’s hope it arrives before patience runs out… And they have a lot!
