Need Help - Missing Chest - DEPULSO PUZZLE ROOM 1

[Magic-Tinkerbell]

After completing all the main/side quests, I wanted to complete the collections. When looking at the map I noticed that a treasure chest was missing. The last chest was in "DEPULSO PUZZLE ROOM 1". After trying for a long time I solved the puzzle and was able to open the treasure chest, but there was no item. got no success and it still shows as missing in the collection.

Does anyone have an idea what to do?

is there a possibility for a respawn?

It's the last achievement for me to complete this game to 100%
