What is the bug? (Genshin Impact)

Good afternoon, what should I do? During the new event with Inazuma, you need to get to the islands. The task starts with Katerina, during this my PC turned off, later I went into the game, but Katerina did not give the task, and in the events it is written that you need to complete the tasks, which I do not have in the tasks and I cannot get it.
