Vibrant visuals got disabled on one of my worlds despite not touching the game and having it updated automatically on ps5 from version 26.3 to version 26.40.
This world uses default packs, with no experience or particular settings turned on asides from Minecraft Education yet was having Vibrant visuals working with it before.
It is impossible for me to change graphics settings for this world and any of its copies I made, as the “Vibrant visuals” option is grey and not possible to interact with. Modifying settings via main menu or turn off/on the game did not worked.
