Greetings,
I have been playing for a good while now ( 6 months roughly) and have reached the Ruby sea. Above water the Map works without so much as a hitch, Quests can be taken, NPC monsters slayn etc. As soon as i enter the Threshhold of the under water location "Tamamizu", either by Aetherite or manually on foot. The game displays the following Error message, before allowing me briefly to still walk the map and then shutting down.

My attempts to resolve this issue so far have includet:
-Running the game without the recommendet Direct X 11 setting from the launcher
-Deleting the files locally and reinstalling the entire game
-Deleting the game completely from my Steam Library and reinstalling it again

off which none have yielded results. Since this Error hinders me from continuing the MsQ i would be very appreciative of any help or solutions.
Thank you for any help in advance
