Switch Nintendo Switch Skull Cavern Stuck

[Sarastardew]

Help! I’m playing on Nintendo switch on a multiplayer game and we accepted and failed the skull cavern invasion quest. Since then the skull cavern has been stuck in hard mode. In previous save files we have been able to beat this challenge but this time we are struggling to even get past level 20!!!
This happened once before in a previous save file and we were able to fix it and I can’t remember how. Any ideas?

We are having this same issue!! We accepted it and failed and it never reverted back, and when we try to interact with the statue at the door it just reads "???". We even reached past floor 100 recently, but didn't have the quest active anymore and it didn't revert. Please help! We are playing version 1.6 (v1.6.15 build 3)
