For those experiencing the crash problem, the only solution at the moment is to go to settings->general management->reset->reset all settings. This will reset all settings on your device but at least in my experience it works as long as I don't reboot my device or free up my phone's memory with device care or any cleaning app.. I don't guarantee this will work with all devices, but at least with Samsung devices it is a temporary fix until NM resolves the game's incompatibility with Android 12.
