Here is a quick breakdown for those of you that haven't sold your souls to pass the bar.
The 2nd Circuit Judges engaged in shenanigans involving the Second Amendment. The victims of those shenanigans finally got the their plea for help to the Supreme Court which told the Second Circuit Judges "redo your work taking into account the ruling we just made in Rahimi (the hand picked Biden administration case that used a domestic abuse case to try and force the Supreme Court to make a politically unpopular choice to either reduce Second Amendment rights or get shit on by the press for "giving guns to wife beaters". It worked to an extent).
In this opinion the 2nd Circuit just came back to the Supreme Court and said, "the Rahimi opinion you asked us to consider does not apply, we are still going to do the exact same thing we had already planned on doing before you got involved, and we will play some more delay games; see you in a few years after hopefully a few of you assholes have died and been replaced by hand picked Kamala Harris zealots that think the Second Amendment was a mistake that needs to be aborted."
