Encountered a destructive bug, the Ascension Trial map cannot be opened.

After killing Barbara in Chapter 2, I picked up the Titan Coins but temporarily dropped them on the ground while cleaning my backpack. Later, I forgot about it. Now that I've leveled up to 60, I can't enter the Ascension Trial map. Even after resetting the map back to Chapter 2 and killing Barbara again, the Titan Coins did not drop, preventing me from continuing the trial. By the way, at that time, I didn't have the Giant's Coin quest, which prevented me from unlocking the trial map. Now there is no way to enter the trial.
