Custom Validation Rule does not work on every 2nd attempt

Validator::extend('available', function ($attribute, $value, $parameters, $validator) {
            $property = Property::find(request('id'));

            if ( ! $property) {
                return true;
            }

            foreach ($property->blockedDates()->get() as $booking) {
                if (
                    Carbon::parse(request()->dates['from']) <= Carbon::parse($booking->departure) &&
                    Carbon::parse(request()->dates['to']) >=  Carbon::parse($booking->arrival)
                ) {
                    return false;
                }
                return true;
            }

            return true;
        });

What I'm doing is I'm checking if your requested dates intersected with the property blocked dates.

My problem is that the Custom Validation Rule does not work on every 2nd attempt.

but when I do this. It works on every request

Validator::extend('available', function ($attribute, $value, $parameters, $validator) {
            return false;
        });
