Why is my $record->save(); not working

Action::make('Run Campaign')
     ->action(function (Campaign $record, Set $set) {
         $set('status_id', CampaignStatusEnum::Run );
         $record->save();
    }),

 Action::make('Pause Campaign')
->action(function (?Model $record, Set $set) {
    $set('status_id', CampaignStatusEnum::Paused );
    $record->save();
})
