Код не выполняется после блока задачи Swift ⇐ IOS

[Anonymous]

Код не выполняется после определенной задачи блокировки в моем коде, который является частью более крупного проекта.
Я не использую do-catch в этой задаче block.
Почему это происходит? Оператор печати, который печатает то, что блок задачи извлекает, в конце задачи и печатает то, что он правильно извлекает. Этот блок задач происходит дважды в этом контроллере представления, однако код не выполняется после запуска в него в первый раз.Just the Task block:
Import UIKit

Task {
guard let venues = try? await getInitialRestaurantVenueInfoWithIfOpenAtSatOrSun201AMDateTimes_FriOrSatAfter2AMForUserPropertiesForMapView(latitude: latitudeForRetrievingData!,
longitude: longitudeForRetrievingData!,
category: "restaurants",
sortBy: "rating",
openAtForSaturday201AMDateTimeAfterFriday2AMForUser: retrieveNextSaturday201AMDateTimeOriginallyInSelectedLocationTimeZoneTimeInUnixTimeRelativeToTodayForSelectedLocation(),
openAtForSunday201AMDateTimeAfterSaturday2AMForUser: retrieveNextSunday201AMDateTimeOriginallyInSelectedLocationTimeZoneTimeInUnixTimeRelativeToTodayForSelectedLocation()) else {return}

self.venues = venues

//Print Check.
print("Print check. venues at the end of the Task block:", venues)
//Prints 'venues', which is an array of classes.
}

//Print Check.
print("Print Check. After Task block.")
//Doesn't print.
