The problem with the Nine World Columns mission (Genshin Impact)

Good afternoon. There was a problem with the mission "Nine World Columns." Opened the dungeon, killed mobs, and chests do not open that is, the inscription "Chest is closed." Restarted the game and PC, changed the characters, teleported back and forth, came from a mobile, but nothing helped (and the game is not very desirable). Please help.
