Пользовательский интерфейс не обновляется данными при первом запуске приложения, но загружается, когда приложение закрыв ⇐ Android

[Anonymous]

У меня возникла проблема: при первом открытии приложения, когда пользователь проходит регистрацию, а затем переходит на главный экран, пользовательский интерфейс не загружает данные из базы данных и зависает на пустом белом экране на неопределенный срок. Но после закрытия и повторного открытия приложения данные загружаются как обычно.
Во время этого я также получаю следующие ошибки в журнале:
kotlinx.coroutines.JobCancellationException: задание было отменено; job=SupervisorJobImpl{Cancelling}@6cd224a
