Same 96s1p, eight modules of twelve, in the original i3 envelope, with the 120 Ah cell. The recall remedy is a module replacement on the car.

NHTSA 22V683: a small number of US 2019-2021 i3 BEV and REx cars built 1 Nov 2018 to 26 May 2021. The pack may not have been built to specification. A short could lead to a thermal event. Remedy is replacement of the affected cell module. BMW's FAQ said owners could keep driving and charging. Not every 120 Ah car.
